  • 00:00:00 - 00:05:00

    The video introduces a networking project series, emphasizing the importance of starting from basic to more complex levels. The presenter encourages viewers to watch the previous video, subscribe to the channel, and highlights the significance of networking projects.

  • 00:05:00 - 00:10:00

    A case study is introduced about a company in Eastern Australia planning to open a new branch. The company requires a separate network for this branch, using only Cisco products and with specific requirements for network design, such as having three departments with separate VLANs and wireless networks.

  • 00:10:00 - 00:15:00

    Detailed requirements for the network design are discussed, including the use of VLANs for department separation, wireless access points for each department, DHCP for automatic IP allocation, and inter-VLAN routing for communication between departments. Subnetting with given base network and requirements is also necessary.

  • 00:15:00 - 00:20:00

    The presenter begins the subnetting process by defining the base network and calculating the number of subnets using a formula. The explanation includes converting the subnet mask to binary and determining the number of bits to borrow.

  • 00:20:00 - 00:25:00

    Continues with binary to decimal conversion to determine the new subnet mask, and establishes the block size for subnetting. The subnet mask and block size help in defining IP address allocations for the network's departments.

  • 00:25:00 - 00:30:00

    Calculates network IDs, broadcast IDs, and host ranges for each subnet, explaining the process of moving from one subnet to another using block size. Each department is allocated a specific range of IP addresses based on these calculations.

  • 00:30:00 - 00:35:00

    The design phase is described with a visual layout of the network components, including routers and switches for each department. VLANs are configured on switches to ensure traffic separation among departments.

  • 00:35:00 - 00:40:00

    The presenter sets up access points for wireless connectivity across departments, ensuring different SSIDs and passphrases for network security. Each department must connect to its specific access point to test network setup.

  • 00:40:00 - 00:45:00

    Router configuration is adjusted to enable trunk interfaces, allowing communication between different VLANs through sub-interfaces. This configuration facilitates inter-VLAN routing necessary for network communication.

  • 00:45:00 - 00:50:00

    DHCP pools are configured on the router for each department, assigning network addresses, default gateways, and DNS settings. This setup ensures devices receive IP addresses automatically and can communicate efficiently.

  • 00:50:00 - 00:57:08

    Testing phase confirms successful network setup, checking IP configurations and connectivity between devices across different VLANs. The project's implementation is portrayed as successful, urging viewers to subscribe and engage with the channel.

    video guys we managed to handle the
  • 00:00:15
    first networking project in our list
  • 00:00:17
    okay and we said we'll beginning from
  • 00:00:19
    the very basic project to a much
  • 00:00:22
    complicated one so guys of course

    based on networking project and other
  • 00:00:59
    domains okay
  • 00:01:00
    so welcome and let's start
  • 00:01:02
    okay
  • 00:01:03
    so i have a problem here
  • 00:01:06
    let me just show you the problem
  • 00:01:09
    this is the problem that i have got the
  • 00:01:12
    problem says
  • 00:01:14
    xyz company is a fast growing company in
  • 00:01:17
    eastern australia with more than 2
  • 00:01:19
    million customers global
  • 00:01:22
    the company deals with selling and
  • 00:01:24
    buying of food items which are which
  • 00:01:27
    which are basically operated from the
  • 00:01:29
    headquarters okay
  • 00:01:31
    the company is intending to open a
  • 00:01:33
    branch near the local village bon alba
  • 00:01:36
    thus the company requires a young i.t
  • 00:01:39
    graduate to design the network for the
  • 00:01:41
    for the branch i mean
  • 00:01:43
    the network is intended to operate
  • 00:01:46
    separately from the
  • 00:01:47
    hq network very importantly the network
  • 00:01:51
    is important
  • 00:01:52
    the network is intended to operate
  • 00:01:54
    separately from the hq network okay
  • 00:01:58
    now being a small network the company is
  • 00:02:01
    the following requirement during
  • 00:02:02
    implementation during design and
  • 00:02:05
    implementation okay
  • 00:02:07
    the company only requires one router and
  • 00:02:10
    one switch for that
  • 00:02:12
    small network okay
  • 00:02:14
    all these products should be cisco
  • 00:02:16
    products okay
  • 00:02:17
    then the company requests that
  • 00:02:21
    branch to have
  • 00:02:23
    three departments which are admin stroke
  • 00:02:26
    id finance stroke hr
  • 00:02:29
    and finally customer service stroke
  • 00:02:32
    reception
  • 00:02:34
    and then but see each department is
  • 00:02:36
    required to be in a different way
  • 00:02:39
    okay
  • 00:02:40
    but the each department is required to
  • 00:02:42
    have wireless network for the users okay
  • 00:02:45
    most devices in the network are required
  • 00:02:48
    to obtain ipv4 address automatically but
  • 00:02:51
    f devices in all the net in all the
  • 00:02:54
    departments are required to communicate
  • 00:02:57
    with each other okay
  • 00:02:59
    now assume the isp gave a base network
  • 00:03:02
    of this one you as a network engineer
  • 00:03:05
    who has been hired design and implement
  • 00:03:08
    a network considering the above
  • 00:03:10
    requirements
  • 00:03:12
    okay guys so this is the case study
  • 00:03:16
    before you can do something you have to
  • 00:03:18
    understand the background of the problem
  • 00:03:20
    and you want to evaluate the problem and
  • 00:03:23
    to identify the possible solution to
  • 00:03:26
    solve that particular problem okay
  • 00:03:29
    there's a company
  • 00:03:31
    that is based in eastern australia
  • 00:03:33
    and you know
  • 00:03:36
    it
  • 00:03:37
    operates
  • 00:03:39
    and it deals with selling and buying
  • 00:03:41
    food items
  • 00:03:43
    and all these operations are done from
  • 00:03:45
    the headquarter
  • 00:03:47
    and i can assume that the company has no
  • 00:03:50
    branch so far and now the company is
  • 00:03:52
    intending to open a branch near the
  • 00:03:55
    local village okay
  • 00:03:56
    because you know
  • 00:03:58
    two million customers from the
  • 00:04:00
    headquarters are too much so
  • 00:04:02
    they're trying to open a branch to
  • 00:04:04
    accommodate other customers so that the
  • 00:04:07
    headquarter
  • 00:04:08
    so that the headquarters cannot be
  • 00:04:10
    flooded okay
  • 00:04:12
    so the company requires just a young i.t
  • 00:04:14
    graduate to design the network for the
  • 00:04:16
    branch
  • 00:04:18
    okay and the network is intended to
  • 00:04:20
    operate separately from the hq this is a
  • 00:04:23
    very important
  • 00:04:24
    point guys
  • 00:04:25
    the network is import the network is
  • 00:04:28
    intended to operate separately from the
  • 00:04:30
    hq network
  • 00:04:32
    basically
  • 00:04:33
    what this means
  • 00:04:35
    is that
  • 00:04:36
    the branch network will be in a
  • 00:04:38
    different autonomous system from the sq
  • 00:04:41
    network okay very important during our
  • 00:04:43
    descent
  • 00:04:44
    and the implementation i mean okay
  • 00:04:46
    then there are some requirements that
  • 00:04:48
    the company requires one router and one
  • 00:04:50
    switch to be used all cisco products
  • 00:04:53
    because you know it's a small network
  • 00:04:56
    very small okay
  • 00:04:58
    then
  • 00:04:59
    three departments which includes this
  • 00:05:01
    one okay
  • 00:05:02
    each department is required to be in
  • 00:05:05
    different vlans
  • 00:05:07
    very important meaning in our
  • 00:05:09
    configuration
  • 00:05:10
    meaning in our additional implementation
  • 00:05:12
    will have different villains three
  • 00:05:14
    values okay because three departments
  • 00:05:17
    different villains
  • 00:05:18
    three department
  • 00:05:20
    three villains okay
  • 00:05:22
    each department is required to have
  • 00:05:24
    wireless network for the users meaning
  • 00:05:27
    at every department we will have
  • 00:05:30
    access point wireless access point to
  • 00:05:32
    provide wi-fi for the users
  • 00:05:35
    then finally part five
  • 00:05:37
    host devices in the network are required
  • 00:05:40
    to obtain
  • 00:05:41
    ip address automatically
  • 00:05:44
    basically to obtain ip address
  • 00:05:46
    automatically we are going to use dcp
  • 00:05:48
    server and we are going to configure the
  • 00:05:50
    router here as our dcp server okay
  • 00:05:54
    now but f which is the final point
  • 00:05:57
    devices in all the departments are
  • 00:05:59
    required to communicate with each error
  • 00:06:02
    you know
  • 00:06:03
    these devices are in different values we
  • 00:06:05
    have three departments
  • 00:06:09
    okay which represents three venues
  • 00:06:11
    so by default devices in different
  • 00:06:14
    villains will not communicate and hence
  • 00:06:16
    we have to implement what is called
  • 00:06:18
    intervalent routing and to enable these
  • 00:06:21
    devices in different valence to
  • 00:06:23
    communicate okay
  • 00:06:25
    so i will list those important points
  • 00:06:27
    down so that we can take the approach
  • 00:06:29
    from there
  • 00:06:30
    and now finally assume that isp gave out
  • 00:06:33
    a basement of provision u.s young
  • 00:06:35
    network engineer who has been hired
  • 00:06:36
    designed and implement a network
  • 00:06:38
    considering the above requirements
  • 00:06:41
    this is the
  • 00:06:42
    base network okay
  • 00:06:44
    and considering the requirements
  • 00:06:48
    the branch is required to have three
  • 00:06:49
    departments
  • 00:06:51
    meaning now we have to do some
  • 00:06:53
    subnetting to allocate
  • 00:06:56
    ip address to each subnet okay so
  • 00:07:00
    basically what i'll start with guys
  • 00:07:04
    is the design part before you can go to
  • 00:07:07
    subnetting and configuration part
  • 00:07:09
    okay
  • 00:07:10
    the company said they require just one
  • 00:07:13
    router okay
  • 00:07:16
    i'll choose 29 11 router
  • 00:07:19
    and place there
  • 00:07:21
    okay
  • 00:07:23
    then
  • 00:07:24
    one switch a cisco switch i'll take one
  • 00:07:27
    switch
  • 00:07:28
    and place here how many departments we
  • 00:07:31
    have free departments
  • 00:07:34
    so
  • 00:07:36
    let's say
  • 00:07:40
    so this is the first department designer
  • 00:07:43
    printer
  • 00:07:44
    the second department is a pc and the
  • 00:07:46
    printer also
  • 00:07:48
    and finally
  • 00:07:50
    the third department is pc and the
  • 00:07:52
    printer also you know
  • 00:07:53
    there are several
  • 00:07:55
    there are several devices so we can
  • 00:07:58
    put them all here
  • 00:08:00
    okay
  • 00:08:01
    this is just a demonstration
  • 00:08:04
    a kind of a prototype
  • 00:08:07
    okay
  • 00:08:08
    so let's go back to the case study
  • 00:08:11
    each department is required to be in
  • 00:08:13
    different values this the country's
  • 00:08:14
    configuration part we will just comment
  • 00:08:16
    to indicate which villain is this
  • 00:08:19
    a department is required to have
  • 00:08:21
    wireless network for the users meaning
  • 00:08:24
    we have to configure access points so
  • 00:08:27
    basically i'll come to wireless devices
  • 00:08:30
    and choose access point for this
  • 00:08:33
    department
  • 00:08:35
    access point for this department and
  • 00:08:38
    finally access find for this department
  • 00:08:40
    and now let's go back
  • 00:08:42
    most devices in the network are required
  • 00:08:44
    to obtain auto that is the configuration
  • 00:08:47
    part devices configuration part
  • 00:08:49
    and now let's do the connection
  • 00:08:53
    let's do the cabling
  • 00:08:55
    i'll use the automatic cable type
  • 00:08:58
    and then from printer the amine from p
  • 00:09:01
    switch to
  • 00:09:02
    access point
  • 00:09:03
    then from this to this
  • 00:09:06
    these are very important project guys
  • 00:09:09
    remember we are going to handle valence
  • 00:09:11
    interval and routing dcp server and
  • 00:09:13
    subnetting
  • 00:09:15
    which are very very important
  • 00:09:17
    and those are things that we have
  • 00:09:19
    learned in our previous classes
  • 00:09:23
    this is a very very important project
  • 00:09:25
    the complexity of these projects will
  • 00:09:27
    increase you know as we handle
  • 00:09:31
    many projects
  • 00:09:32
    so consider this one as a simple project
  • 00:09:35
    the next one will be a much little bit
  • 00:09:37
    uh
  • 00:09:39
    complicated than this one
  • 00:09:42
    and hence very very important
  • 00:09:47
    very very important
  • 00:09:49
    okay
  • 00:09:51
    so we are done
  • 00:09:52
    doing the descent part
  • 00:09:55
    as you can see we have a router as a
  • 00:09:58
    required a switch
  • 00:10:00
    and the host devices
  • 00:10:02
    and these devices
  • 00:10:04
    department one two three
  • 00:10:06
    and basically just spread the boundaries
  • 00:10:10
    so that
  • 00:10:12
    we can know which department is this
  • 00:10:15
    so that is a let's say
  • 00:10:18
    there and uh
  • 00:10:20
    yes it's used green
  • 00:10:24
    another one here
  • 00:10:28
    and finally the flash department
  • 00:10:31
    at least
  • 00:10:32
    blue
  • 00:10:37
    okay
  • 00:10:38
    what i'll do next is just to comment
  • 00:10:43
    the first department was
  • 00:10:46
    admin stroke as i t
  • 00:10:50
    so this is administrative
  • 00:10:53
    admin
  • 00:10:56
    stroke i think
  • 00:11:00
    then
  • 00:11:01
    we have finance

    stroke hr
  • 00:11:06
    we have customer service cs stroke
  • 00:11:09
    reception
  • 00:11:12
    okay and then what else can we comment
  • 00:11:15
    let me just go to back to the case study
  • 00:11:18
    one router three departments deeper oh
  • 00:11:20
    valence so let's assume
  • 00:11:23
    i
  • 00:11:24
    admin
  • 00:11:26
    this department belongs to villain 10 so
  • 00:11:29
    let's see vlan 10
  • 00:11:32
    this belongs to vlan 20
  • 00:11:35
    and finally here belongs to villain 30
  • 00:11:39
    okay
  • 00:11:43
    so
  • 00:11:44
    we are good to go
  • 00:11:46
    and start the practical part of this one
  • 00:11:49
    subnetting and configuration
  • 00:11:54
    okay so the next step guys is to go for
  • 00:11:58
    subnetting
  • 00:12:00
    okay
  • 00:12:01
    and for submitting guys i will open one
  • 00:12:03
    document and guide you through it so
  • 00:12:06
    i'll open word
  • 00:12:12
    we will do submitting based on the
  • 00:12:13
    requirements
  • 00:12:16
    okay
  • 00:12:17
    so basically what you have to list
  • 00:12:19
    during subnetting the best network
  • 00:12:25
    the base network
  • 00:12:27
    which is
  • 00:12:31
    192.168.1.0
  • 00:12:35
    okay
  • 00:12:36
    then the number of departments required
  • 00:12:39
    or the number of subnets required number
  • 00:12:41
    of
  • 00:12:43
    subnets
  • 00:12:45
    is equal to three
  • 00:12:47
    okay
  • 00:12:49
    so
  • 00:12:50
    these two will act as the guideline
  • 00:12:54
    for subnetting
  • 00:12:56
    okay
  • 00:12:57
    guys
  • 00:12:59
    in the previous project that you handle
  • 00:13:01
    it is very similar to this one
  • 00:13:03
    because
  • 00:13:05
    in that particular project we were also
  • 00:13:07
    given a base network
  • 00:13:09
    and the number of required subnets
  • 00:13:12
    okay in that case there were two and now
  • 00:13:14
    here there are three and we said to find
  • 00:13:17
    the number of subnet guys
  • 00:13:19
    there is a formula
  • 00:13:22
    okay
  • 00:13:26
    okay
  • 00:13:28
    and that formula is
  • 00:13:30
    number of subnet
  • 00:13:35
    is equal to 2
  • 00:13:37
    raised to power n
  • 00:13:39
    okay
  • 00:13:40
    where this n
  • 00:13:42
    will represent the number of borrowed
  • 00:13:44
    bits the number of borrowed network bits
  • 00:13:48
    okay
  • 00:13:50
    so
  • 00:13:51
    2
  • 00:13:53
    raised to n
  • 00:13:56
    is equal to 3
  • 00:13:58
    number of subnets 3. so this is the
  • 00:14:01
    formula and n here represent the number
  • 00:14:03
    of ball bits the number of borrowed
  • 00:14:05
    network bits so
  • 00:14:07
    which value here that tourist that value
  • 00:14:11
    will give us
  • 00:14:12
    three so let's try
  • 00:14:14
    two raised to 0 will give us 1 that's
  • 00:14:17
    wrong
  • 00:14:18
    okay
  • 00:14:19
    2 raised to 1 will give us 2 that is
  • 00:14:21
    very less you know when you are doing
  • 00:14:23
    calculation
  • 00:14:24
    the number n should give
  • 00:14:27
    a result of
  • 00:14:29
    that is equivalent to the number of
  • 00:14:32
    subunits or
  • 00:14:34
    more than the number of subnets okay but
  • 00:14:37
    you should not give a value that is less
  • 00:14:39
    than okay
  • 00:14:40
    the number of subnets
  • 00:14:42
    the number of required subnets
  • 00:14:44
    okay so two let's try two raise to power
  • 00:14:47
    two that will give us four the number of
  • 00:14:50
    departments and you say the number of
  • 00:14:52
    the pattern the number of subnets you
  • 00:14:55
    know the formula here should give a
  • 00:14:57
    value which is equivalent to the
  • 00:14:59
    required value here or mother okay
  • 00:15:04
    zero is less one is less two is mother
  • 00:15:08
    okay meaning
  • 00:15:10
    and
  • 00:15:11
    must just be two okay
  • 00:15:13
    so
  • 00:15:16
    n is equal to
  • 00:15:19
    two
  • 00:15:20
    and we said guys
  • 00:15:23
    and represent the number of borrowed
  • 00:15:24
    bits the number net borrowed network
  • 00:15:28
    bits let's go back to our base network
  • 00:15:32
    this is a class c address okay and for
  • 00:15:35
    class c address the subject mask let's
  • 00:15:38
    just say class c
  • 00:15:41
    subnet mask should be 255
  • 00:15:44
    255.255.0
  • 00:15:47
    okay and when you convert this to binary
  • 00:15:50
    guys when you convert this decimal
  • 00:15:53
    value
  • 00:15:55
    to binary i mean you will get a value
  • 00:15:57
    that is equivalent to
  • 00:15:59
    sorry
  • 00:16:03
    the first octet will be
  • 00:16:06
    eight ones one two three four five six
  • 00:16:09
    seven eight okay because
  • 00:16:12
    two point five all the bits are turned
  • 00:16:14
    on okay
  • 00:16:16
    and now the second octet also will be
  • 00:16:19
    eight bits turned on
  • 00:16:21
    the same for
  • 00:16:22
    third update eight beans bit stand on
  • 00:16:25
    okay and now for the last octet guys you
  • 00:16:28
    see it's zero
  • 00:16:30
    no beats
  • 00:16:32
    is turned on so it's all zero zero one
  • 00:16:35
    two three four five six seven eight
  • 00:16:38
    okay
  • 00:16:40
    so
  • 00:16:40
    normally
  • 00:16:42
    this is the subnet mask
  • 00:16:45
    of a class c address plus
  • 00:16:49
    the binary form of it
  • 00:16:51
    but we have two
  • 00:16:53
    borrowed bits to satisfy the requirement
  • 00:16:56
    here guys what do we do
  • 00:17:00
    this is the normal subnet mask of a
  • 00:17:02
    class c address but now to satisfy the
  • 00:17:05
    subnet
  • 00:17:07
    requirement
  • 00:17:08
    we have to borrow two network bits so
  • 00:17:11
    the new binary form will be remember
  • 00:17:14
    this is the first binary form okay now
  • 00:17:17
    the new binary form will be i'm copying
  • 00:17:20
    it
  • 00:17:22
    after borrowing
  • 00:17:26
    after borrowing
  • 00:17:28
    after after book
  • 00:17:30
    after borrowing
  • 00:17:34
    two bits
  • 00:17:37
    okay
  • 00:17:39
    now new
  • 00:17:41
    binary form
  • 00:17:44
    is equal to this one then we borrow two
  • 00:17:48
    bits
  • 00:17:49
    two
  • 00:17:50
    network bits the network bits are
  • 00:17:52
    represented by one
  • 00:17:54
    one one okay
  • 00:17:56
    now we have border two
  • 00:17:58
    bits okay from the host
  • 00:18:00
    portion
  • 00:18:01
    okay
  • 00:18:02
    now the network id will be represented
  • 00:18:05
    from this point
  • 00:18:07
    from the last one to
  • 00:18:09
    the first one here okay
  • 00:18:12
    from here
  • 00:18:13
    to here
  • 00:18:14
    sorry
  • 00:18:16
    to here okay now this will be the
  • 00:18:18
    network bit and this will be the old
  • 00:18:23
    portion
  • 00:18:24
    so guys
  • 00:18:25
    to carry on with subnetting let's
  • 00:18:28
    convert this back to
  • 00:18:30
    decimal to convert this back to the
  • 00:18:32
    decimal guys
  • 00:18:34
    an octave that has it's all
  • 00:18:38
    beats turn on
  • 00:18:39
    represent a banner represent a decimal
  • 00:18:42
    value of two five five then two five
  • 00:18:44
    five then two five five for these three
  • 00:18:48
    okay
  • 00:18:49
    now let's go for the last
  • 00:18:53
    octet
  • 00:18:54
    okay and convert this to
  • 00:19:01
    decimal
  • 00:19:02
    we want to convert we want to convert
  • 00:19:05
    this value in decimal and now we start
  • 00:19:08
    put this into we convert the binary into
  • 00:19:12
    decimal to find the last octet of the
  • 00:19:14
    new
  • 00:19:16
    subnet mask this is the new subnet mask
  • 00:19:18
    let me just say new
  • 00:19:20
    sm okay
  • 00:19:24
    raised to 0 times 0
  • 00:19:25
    is 0
  • 00:19:27
    2 raised to 1 times 0
  • 00:19:30
    is 0
  • 00:19:31
    2 raised to 2
  • 00:19:33
    times 0 is 0 2 raised to 3 times 0 is 0
  • 00:19:37
    2 is 2
  • 00:19:39
    4 times 0 is 0 2 raised to 5 times 0 is
  • 00:19:44
    0 2 raised to 6 times 1
  • 00:19:48
    is
  • 00:19:49
    64
  • 00:19:50
    plus 2 raised to 7
  • 00:19:53
    times 1 is 128 so it's 128 plus 64.
  • 00:19:58
    and we get 192
  • 00:20:02
    conversion of binary into decimal guys
  • 00:20:04
    pretty much simple if you have any
  • 00:20:06
    problem kindly research about it
  • 00:20:09
    google and you will understand it better
  • 00:20:12
    okay
  • 00:20:13
    so this is our new subject mask and
  • 00:20:16
    basically we're going to use the subnet
  • 00:20:18
    mask guys
  • 00:20:19
    plus this base network now to find
  • 00:20:23
    the num
  • 00:20:24
    profile
  • 00:20:26
    to allocate ip address at every
  • 00:20:30
    department okay
  • 00:20:32
    all right so
  • 00:20:34
    we said in our previous class
  • 00:20:36
    that's the class of subnetting
  • 00:20:40
    whenever a subnet mask ends with 92 192
  • 00:20:44
    i mean now the block size is
  • 00:20:47
    let me show you subnet mask
  • 00:20:49
    block size calculation
  • 00:20:52
    this is it
  • 00:20:54
    when subnet mask ends with 128 the block
  • 00:20:56
    says one always wanted to name when
  • 00:20:59
    subnet mask ends with 188 the block size
  • 00:21:02
    is 128 182 becomes 64.
  • 00:21:06
    224 becomes 32 and so and so forth and
  • 00:21:09
    now our subject mask ends with 192.
  • 00:21:14
    now our block size is 164 and now
  • 00:21:18
    the blockers will tell us how to move
  • 00:21:21
    from one subnet to another okay
  • 00:21:24
    all right so let's go
  • 00:21:26
    one and two represent a boxes of 64
  • 00:21:30
    boxes
  • 00:21:33
    is equal to 64.
  • 00:21:35
    okay
  • 00:21:37
    now let's find
  • 00:21:39
    the ipl location for each depart
  • 00:21:42
    now
  • 00:21:44
    now let's find ipl location for each
  • 00:21:47
    department okay
  • 00:21:51
    first department first submit
  • 00:21:55
    okay
  • 00:21:56
    second subnet
  • 00:22:00
    and finally third subnet because we have
  • 00:22:02
    three departments
  • 00:22:06
    okay
  • 00:22:07
    so the first department guys
  • 00:22:10
    we always say network id
  • 00:22:14
    network id
  • 00:22:17
    broadcast id
  • 00:22:21
    id
  • 00:22:23
    okay
  • 00:22:25
    and uh
  • 00:22:29
    or strange
  • 00:22:33
    okay
  • 00:22:35
    then finally sub no
  • 00:22:37
    now
  • 00:22:38
    we use this so for the network id guys
  • 00:22:42
    you know
  • 00:22:44
    these are block size
  • 00:22:46
    and the network id guys will be this one
  • 00:22:48
    okay dot zero
  • 00:22:50
    should ensure that the first network id
  • 00:22:53
    begins from dot z okay
  • 00:22:56
    and now
  • 00:22:58
    the second network id should begin from
  • 00:23:02
    the block size plus this one
  • 00:23:04
    okay
  • 00:23:05
    which is let me just copy this first
  • 00:23:10
    and paste here
  • 00:23:13
    now
  • 00:23:15
    in the second subnet
  • 00:23:18
    the network id will be
  • 00:23:21
    this one plus the block size which is
  • 00:23:23
    64. okay
  • 00:23:26
    can you hear me
  • 00:23:28
    can you can you understand that
  • 00:23:31
    and now finally on the third department
  • 00:23:36
    let me just paste this
  • 00:23:38
    the network id will be the block size
  • 00:23:41
    which is 64
  • 00:23:42
    okay
  • 00:23:43
    plus
  • 00:23:45
    the network id of
  • 00:23:49
    there is
  • 00:23:50
    previous subnet which is
  • 00:23:52
    128
  • 00:23:54
    and now from this point we can calculate
  • 00:23:57
    the broadcast id and the range
  • 00:24:00
    of valid host
  • 00:24:02
    ids okay
  • 00:24:04
    to find
  • 00:24:06
    the broadcast id guys
  • 00:24:07
    the broadcast id will be the last
  • 00:24:11
    ip address to move to the next
  • 00:24:13
    subnet
  • 00:24:14
    if this is the next subnet now the last
  • 00:24:17
    ip address wii is 182.168.1.63
  • 00:24:20
    [Music]
  • 00:24:24
    the last iprs to move to the
  • 00:24:26
    next
  • 00:24:28
    subnet
  • 00:24:29
    okay
  • 00:24:30
    and now
  • 00:24:33
    broadcast id here will be
  • 00:24:35
    the last ip to move the next subnet
  • 00:24:38
    which is which is 103.168.1.127
  • 00:24:43
    okay
  • 00:24:44
    all right and now here guys you know
  • 00:24:47
    we don't
  • 00:24:50
    to find the broadcast id here guys
  • 00:24:53
    if you have not calculated the fourth
  • 00:24:55
    subnet just add 164 here and subtract
  • 00:24:58
    one okay
  • 00:25:01
    so let's just add
  • 00:25:02
    63 here
  • 00:25:05
    which will be
  • 00:25:06
    191 quantity 168.1.191
  • 00:25:12
    191 that will be the broadcast id
  • 00:25:16
    of the third subnet okay
  • 00:25:18
    and now let's find the range of valid
  • 00:25:21
    host the range of valid host guys lies
  • 00:25:24
    between the network id and broadcast id
  • 00:25:26
    so the network id is
  • 00:25:30
    12.168.1.0 but now the range of valid os
  • 00:25:33
    lies in between meanings.1
  • 00:25:36
    to
  • 00:25:37
    192.168.1.62
  • 00:25:39
    [Music]
  • 00:25:42
    in between
  • 00:25:43
    these two
  • 00:25:45
    okay 0 to 63 so the range of valid from
  • 00:25:49
    dot one to
  • 00:25:50
    dot 62 okay the same for
  • 00:25:54
    for the second segment i'll copy paste
  • 00:25:57
    i'll paste it and say
  • 00:26:00
    65 now
  • 00:26:02
    65
  • 00:26:03
    subtract 1 here 126
  • 00:26:06
    126
  • 00:26:08
    and finally
  • 00:26:09
    the third subnet will paste
  • 00:26:12
    and say here is 129 you had one here
  • 00:26:15
    subtract one here 129
  • 00:26:18
    and now subtract one here which is a 190
  • 00:26:21
    okay
  • 00:26:22
    now guys we are done
  • 00:26:24
    okay we can now go back to
  • 00:26:26
    the configuration part
  • 00:26:28
    we are done with subnetting all right
  • 00:26:33
    this is the first subnet and the first
  • 00:26:35
    subnet
  • 00:26:36
    the network id is 182.168.1.0
  • 00:26:43
    so
  • 00:26:46
    the
  • 00:26:47
    so this is the subnet mask
  • 00:26:49
    and when you convert it and when you
  • 00:26:52
    convert it into a slash notation you'll
  • 00:26:56
    find the value which is so this is the
  • 00:26:58
    binary
  • 00:26:59
    this is 8 8 8 plus 2
  • 00:27:04
    8 16 24 plus this two which is a 26 okay
  • 00:27:10
    a subnet mask of this one represent a
  • 00:27:12
    slash notation of
  • 00:27:14
    26 okay
  • 00:27:15
    so i'll go back to get tracer and finish
  • 00:27:19
    commenting slash 26
  • 00:27:22
    then i'll go back here again and say now
  • 00:27:24
    the network is 102.168.1.64
  • 00:27:30
    26
  • 00:27:31
    and finally here
  • 00:27:33
    192.168.
  • 00:27:38
    1.128 shows 26 okay
  • 00:27:42
    the subnets
  • 00:27:44
    network at every subnet
  • 00:27:47
    okay we are following here the first
  • 00:27:49
    subnet the network id was
  • 00:27:52
    here as you can see second one dot 64
  • 00:27:55
    third one dot 60 dot 128 timing and the
  • 00:27:58
    subnet mask for all is this one which is
  • 00:28:01
    represented by slash 26 notation so i'll
  • 00:28:06
    go back to the configuration part
  • 00:28:08
    so guys we are done with subreddit with
  • 00:28:10
    the comments
  • 00:28:12
    and let's go back to the problem
  • 00:28:16
    the first case is done
  • 00:28:18
    second one is done
  • 00:28:20
    each department is required to be in
  • 00:28:21
    different villains now the configuration
  • 00:28:24
    part begins let's
  • 00:28:26
    configure vlans how do we configure vlan
  • 00:28:30
    and where do we configure vlan we
  • 00:28:32
    configure vlans in the switches okay so
  • 00:28:35
    click on the switch
  • 00:28:38
    then you come to command li
  • 00:28:41
    enable
  • 00:28:42
    config configure
  • 00:28:45
    okay
  • 00:28:47
    then
  • 00:28:49
    so i will get the interfaces which is a
  • 00:28:52
    gig 04 this is gig 0 2 and finally gig
  • 00:28:55
    03
  • 00:28:56
    okay so i'll go to the same switch and
  • 00:28:58
    say
  • 00:29:00
    interface
  • 00:29:01
    gig
  • 00:29:02
    interface range because we want to
  • 00:29:04
    configure the same parameter to those
  • 00:29:05
    particular indexes
  • 00:29:08
    interface fp0 slash
  • 00:29:10
    two to four
  • 00:29:12
    i'm very sorry it was a phase zero slash
  • 00:29:14
    not a gig
  • 00:29:16
    okay
  • 00:29:17
    eager for the routers
  • 00:29:21
    so interface range this one
  • 00:29:24
    and you hit enter and now switch point
  • 00:29:28
    mode
  • 00:29:29
    access how to configure
  • 00:29:32
    valence
  • 00:29:34
    you enter that interface then you change
  • 00:29:36
    that interface into access mode then
  • 00:29:39
    after changing it into access mode now
  • 00:29:41
    you assign the villar number now
  • 00:29:43
    switchboard
  • 00:29:45
    access
  • 00:29:46
    vlan
  • 00:29:48
    10
  • 00:29:50
    as you can see access villain doesn't
  • 00:29:51
    exist
  • 00:29:52
    creating vlan 10
  • 00:29:54
    and we are done
  • 00:29:56
    assigning vlan
  • 00:29:57
    to these interfaces so let's go to the
  • 00:30:00
    second interfaces which are a phaser
  • 00:30:03
    five
  • 00:30:05
    six
  • 00:30:06
    and seven
  • 00:30:07
    and ascend to vlan 20.
  • 00:30:09
    so i'll just try to retrieve the above
  • 00:30:11
    configuration
  • 00:30:13
    okay
  • 00:30:14
    effects class five to seven
  • 00:30:17
    okay switchboard mode access
  • 00:30:19
    then switch part access vlan
  • 00:30:22
    20 very simple
  • 00:30:25
    then finally
  • 00:30:29
    which interfaces are these
  • 00:30:31
    this this one is a
  • 00:30:34
    10
  • 00:30:35
    nine
  • 00:30:37
    and eight so it's eight to ten
  • 00:30:41
    eight to ten
  • 00:30:44
    switchboard mode access then switchbot
  • 00:30:46
    access
  • 00:30:48
    vlan 30
  • 00:30:49
    [Music]
  • 00:30:50
    do right
  • 00:30:52
    exit
  • 00:30:55
    do show start
  • 00:30:57
    as you can see guys
  • 00:30:59
    we have assigned
  • 00:31:01
    these interfaces to
  • 00:31:03
    number as you can see slash two and
  • 00:31:05
    slash three valentine
  • 00:31:08
    i mean
  • 00:31:10
    i mean
  • 00:31:11
    slash two to four valentine
  • 00:31:14
    five to seven last vlan 20 i mean
  • 00:31:18
    and finally
  • 00:31:22
    8 to 10 villain 30 okay
  • 00:31:25
    so we are done configuring vlans let's
  • 00:31:28
    go back to the problem
  • 00:31:30
    each department is required to have
  • 00:31:32
    wireless for the users okay as you can
  • 00:31:35
    see guys we have
  • 00:31:37
    placed the wireless access points at
  • 00:31:40
    every department and now let's configure
  • 00:31:42
    them we configure password and ssid the
  • 00:31:46
    wifi name okay
  • 00:31:49
    start from that one and you come to
  • 00:31:50
    config and port one okay
  • 00:31:53
    but one let's say the name is uh
  • 00:31:56
    that is the admin
  • 00:31:59
    admin wi-fi
  • 00:32:01
    and the password should be the
  • 00:32:03
    authentication mechanism should be wpa2
  • 00:32:06
    psk okay
  • 00:32:08
    and let's say admin
  • 00:32:12
    at one two three okay it's done
  • 00:32:15
    let's configure the third at the second
  • 00:32:18
    access point i mean
  • 00:32:19
    you come to part one and say let's say
  • 00:32:21
    this one is finance
  • 00:32:25
    finance
  • 00:32:26
    wi-fi
  • 00:32:28
    and password
  • 00:32:30
    should be let's say f
  • 00:32:33
    finance
  • 00:32:34
    at one two three
  • 00:32:37
    and finally the third access point
  • 00:32:41
    come to config
  • 00:32:42
    bot1
  • 00:32:45
    the name should be
  • 00:32:47
    cs
  • 00:32:48
    wi-fi
  • 00:32:51
    and the password
  • 00:32:53
    should be
  • 00:32:54
    cs at one two three we are done guys
  • 00:32:59
    we are
  • 00:33:00
    sorry sorry sorry sorry sorry
  • 00:33:06
    the password should be a minimum of
  • 00:33:07
    eight words
  • 00:33:09
    so i'll go back and reconfigure it again
  • 00:33:15
    i'll configure the password again and
  • 00:33:17
    say
  • 00:33:18
    see
  • 00:33:21
    a customer
  • 00:33:25
    at one two three
  • 00:33:27
    okay we're done so let's go back to the
  • 00:33:30
    problem again and see
  • 00:33:32
    all devices in the network are required
  • 00:33:34
    to obtain ipv4 address automatically
  • 00:33:38
    devices in all the departments are
  • 00:33:40
    required to communicate with each other
  • 00:33:42
    guys
  • 00:33:43
    to obtain ipv4 address automatically
  • 00:33:45
    that is dtp server implementation
  • 00:33:48
    for the devices in different vlans to
  • 00:33:50
    communicate that is interval and routing
  • 00:33:53
    so let's go to the router and configure
  • 00:33:55
    that too okay
  • 00:33:57
    so i'll go back to the configuration
  • 00:33:59
    part
  • 00:34:00
    and guys before we can proceed
  • 00:34:04
    i want to explain something you know
  • 00:34:08
    these parts here that are connected to
  • 00:34:10
    the host devices at every department
  • 00:34:12
    their access points
  • 00:34:14
    and we said accessport can only access
  • 00:34:17
    one villain at a time
  • 00:34:19
    okay
  • 00:34:20
    so you know
  • 00:34:26
    during communication in the network
  • 00:34:29
    the traffic will be going to the router
  • 00:34:32
    then coming back
  • 00:34:34
    for example from pc 0
  • 00:34:36
    the traffic will be going from pc 0
  • 00:34:38
    through the switch to the router then
  • 00:34:40
    coming from the router to switch to the
  • 00:34:42
    destination
  • 00:34:45
    and now the traffic that will be passing
  • 00:34:48
    this interface
  • 00:34:49
    will have
  • 00:34:51
    various vlan id for example the traffic
  • 00:34:54
    from this department will be having
  • 00:34:58
    will have
  • 00:34:59
    a villain idea finland 10 from here vlan
  • 00:35:03
    20
  • 00:35:05
    and from here we'll learn that
  • 00:35:07
    and this interface
  • 00:35:10
    should be a trunk interface because a
  • 00:35:12
    trunk interface
  • 00:35:14
    allows
  • 00:35:15
    passage of multiple vlogs so this is
  • 00:35:20
    f zero slash one
  • 00:35:23
    [Music]
  • 00:35:26
    so interface f a little
  • 00:35:38
    now we are done with everything on the
  • 00:35:40
    switch so
  • 00:35:42
    any configuration is
  • 00:35:44
    so any configuration that is remaining
  • 00:35:47
    is
  • 00:35:48
    in the router
  • 00:35:50
    and we will go on the router
  • 00:35:52
    and start the
  • 00:35:53
    and start configuring
  • 00:35:55
    what is required okay so i'll click on
  • 00:35:57
    the router
  • 00:35:59
    cli
  • 00:36:01
    so you know
  • 00:36:02
    the first configuration that we'll do is
  • 00:36:04
    to turn this interface up it's in
  • 00:36:07
    shutdown by default
  • 00:36:10
    so
  • 00:36:12
    enable
  • 00:36:14
    config
  • 00:36:17
    interface
  • 00:36:18
    gig i hope it is gig 0 0
  • 00:36:22
    gig 0 0
  • 00:36:24
    yeah so it's geek0
  • 00:36:28
    no shutdown
  • 00:36:30
    and do right
  • 00:36:33
    okay
  • 00:36:35
    we are done so what's remaining
  • 00:36:37
    basically is to configure intervalon and
  • 00:36:39
    dhcp server we'll start with the
  • 00:36:41
    intervalon
  • 00:36:43
    routing
  • 00:36:44
    okay and to configure interval and
  • 00:36:46
    writing guys we said from a single
  • 00:36:49
    physical interface we create
  • 00:36:52
    multiple sub interfaces for example this
  • 00:36:56
    is gabe00 so from this interface we will
  • 00:37:00
    as we will create
  • 00:37:02
    sub interfaces and assign ip address
  • 00:37:05
    that will act as a default gateway to
  • 00:37:08
    the respective villa
  • 00:37:11
    okay the first thing is to create a sub
  • 00:37:13
    interface okay
  • 00:37:15
    let's go on
  • 00:37:18
    exit
  • 00:37:19
    how do you create a sub interface
  • 00:37:22
    kindly take note on which interface is
  • 00:37:24
    connected to your network okay
  • 00:37:27
    gig zero zero so
  • 00:37:30
    interface
  • 00:37:31
    gig
  • 00:37:33
    zero zero then to create a sub interface
  • 00:37:36
    this is vlan 10 and to create a server
  • 00:37:38
    interface for valentine let's say gig 0
  • 00:37:41
    0
  • 00:37:42
    dot
  • 00:37:43
    10 okay a sub interface from this
  • 00:37:46
    physical interface okay
  • 00:37:49
    and hit enter
  • 00:37:49
    [Music]
  • 00:37:51
    then
  • 00:37:53
    after creating a sub interface guys the
  • 00:37:55
    most important part is to
  • 00:37:58
    specify encapsulation
  • 00:38:01
    dot
  • 00:38:03
    one cube okay dot one q then the vlan
  • 00:38:06
    number
  • 00:38:08
    encapsulation dot one queue and the vlan
  • 00:38:11
    number for vlan 10
  • 00:38:13
    the first
  • 00:38:14
    command was to create a sub interface
  • 00:38:17
    that is similar to the villain number
  • 00:38:18
    dot 10 yeah is vlan 10 okay then
  • 00:38:21
    encapsulation dot one q
  • 00:38:24
    the v number which is vlan 10 okay
  • 00:38:26
    then we want
  • 00:38:33
    we want to assign this sub and interface
  • 00:38:36
    as a default gateway for this vlan and
  • 00:38:39
    now we are sending ip address to this
  • 00:38:41
    [Music]
  • 00:38:43
    interface that ip address will act as a
  • 00:38:46
    default gateway for this
  • 00:38:48
    villa okay for this subnet and we said
  • 00:38:51
    it for first
  • 00:38:53
    and we said for the first subnet the
  • 00:38:55
    range of valid host id start from
  • 00:38:59
    dot one so let's say the router text dot
  • 00:39:02
    one okay
  • 00:39:04
    the router's interface
  • 00:39:07
    that interface 192.168.1.1
  • 00:39:12
    and now subnet mask guys we said
  • 00:39:14
    255.255.255.192
  • 00:39:20
    don't forget
  • 00:39:22
    this was our subnet mask
  • 00:39:24
    for all the subnets okay
  • 00:39:27
    and you hit enter so let's go to the
  • 00:39:29
    second interface
  • 00:39:31
    which is
  • 00:39:32
    [Music]
  • 00:39:34
    so
  • 00:39:35
    interface
  • 00:39:36
    the same physical interface so you hit
  • 00:39:39
    sub interface
  • 00:39:40
    interface gig zero zero dot
  • 00:39:44
    the second vlan which is
  • 00:39:47
    which id vlan 20
  • 00:39:49
    dot vlan 20 and you hit enter
  • 00:39:52
    then encapsulation
  • 00:39:53
    [Music]
  • 00:39:54
    dot 1q 20 the vlan number guys don't
  • 00:39:58
    forget and you hit enter and now you
  • 00:40:00
    assign appearance to this interface
  • 00:40:02
    let me try to retrieve the above
  • 00:40:04
    configuration
  • 00:40:06
    and to send a p address to this
  • 00:40:08
    interface guys we said in the first
  • 00:40:11
    in the second subnet
  • 00:40:13
    the range of valid oscillators from
  • 00:40:17
    65
  • 00:40:18
    okay
  • 00:40:20
    so they let the routers interface
  • 00:40:23
    the created sub interface to take
  • 00:40:25
    65 okay and hit enter do that
  • 00:40:30
    exit
  • 00:40:31
    and now finally we create a sub
  • 00:40:33
    interface for this villa
  • 00:40:36
    which is villain 30
  • 00:40:41
    dot 30
  • 00:40:42
    then
  • 00:40:43
    encapsulation
  • 00:40:45
    dot 1 q 30 the villain id okay
  • 00:40:49
    and i p address should be
  • 00:40:55
    for the third subnet the ip address the
  • 00:40:58
    range of valid appearance for host
  • 00:41:01
    the range of osmo diaper should start
  • 00:41:04
    from 129 okay
  • 00:41:08
    okay
  • 00:41:09
    so the router's interface the sub
  • 00:41:11
    interface will take
  • 00:41:13
    dot 129
  • 00:41:15
    and you hit enter
  • 00:41:16
    do right
  • 00:41:19
    exit
  • 00:41:20
    we are done configuring interval and
  • 00:41:23
    routing and as you can check
  • 00:41:25
    do show start
  • 00:41:28
    sorry
  • 00:41:32
    now
  • 00:41:35
    as you can see guys we have created how
  • 00:41:37
    many sub interfaces three sub interfaces
  • 00:41:40
    from this physical interface dot 10.20
  • 00:41:44
    under 30. for the 10 guys represent
  • 00:41:49
    the first subnet with the you know
  • 00:41:51
    billionaire villain id is indicated here
  • 00:41:53
    plus
  • 00:41:55
    the peer address of the default gateway
  • 00:41:57
    okay
  • 00:41:58
    all right so what's remaining guys is to
  • 00:42:02
    configure dhcp server
  • 00:42:04
    guys to configure the sap server we said
  • 00:42:08
    [Music]
  • 00:42:12
    the first thing is to enable dcp service
  • 00:42:15
    on that particular device okay but you
  • 00:42:18
    know on the cisco devices
  • 00:42:21
    by default it's enabled so i'll go back
  • 00:42:23
    to the router
  • 00:42:25
    exit
  • 00:42:28
    and say service
  • 00:42:31
    dhcp
  • 00:42:33
    this command here will be
  • 00:42:35
    will enable tcp service okay
  • 00:42:39
    then after you have enabled dhcp service
  • 00:42:42
    on that particular route i mean
  • 00:42:45
    after you have the enable dcp service on
  • 00:42:48
    that particular device
  • 00:42:51
    now you create ports okay
  • 00:42:54
    for example
  • 00:42:55
    this is admin this is finance and
  • 00:42:58
    finally customer care stroke reception
  • 00:43:01
    okay
  • 00:43:03
    for example
  • 00:43:06
    so this will be tool admin just click
  • 00:43:10
    using with command ip
  • 00:43:13
    dhcp
  • 00:43:15
    pool okay
  • 00:43:16
    admin
  • 00:43:18
    say admin
  • 00:43:19
    tool okay hit enter
  • 00:43:22
    and now after you have created this pool
  • 00:43:25
    guys it is it represent this subnet okay
  • 00:43:31
    now let's assign a network
  • 00:43:33
    address to the pool that we have created
  • 00:43:37
    the network should be you just say
  • 00:43:39
    network
  • 00:43:41
    192.168.1.0
  • 00:43:43
    [Music]
  • 00:43:45
    now the network you don't place ip
  • 00:43:48
    address here okay
  • 00:43:49
    plus the subnet mask which is a 26
  • 00:43:52
    notation
  • 00:43:53
    255.25
  • 00:43:57
    255.255.192
  • 00:44:02
    slash 26 notation and you hit enter
  • 00:44:05
    after that you give a default gateway
  • 00:44:08
    default gateway the default gateway guys
  • 00:44:12
    will be the ip address of that sub
  • 00:44:14
    interface that we created and assigned
  • 00:44:17
    to that particular failure which is the
  • 00:44:19
    chain this the ip address of this urban
  • 00:44:22
    interface not 10.
  • 00:44:24
    it was
  • 00:44:25
    1.1 okay
  • 00:44:27
    very simple
  • 00:44:30
    1218.1.1
  • 00:44:34
    and now dns
  • 00:44:36
    server
  • 00:44:37
    let's give it uh the same as ip 192.1
  • 00:44:40
    [Music]
  • 00:44:41
    168.1.1
  • 00:44:43
    hit enter and now domain name
  • 00:44:47
    the main name
  • 00:44:48
    let's say admin
  • 00:44:52
    dot com
  • 00:44:54
    and exit
  • 00:44:56
    we're done
  • 00:44:57
    okay
  • 00:44:58
    and now these devices here will be
  • 00:45:00
    assigned ip address automatically let's
  • 00:45:04
    move to the second subnet okay
  • 00:45:07
    in which we will create another pool
  • 00:45:11
    so
  • 00:45:11
    in the second subnet we'll create a pool
  • 00:45:13
    called ipdc people
  • 00:45:16
    pull let's say finance
  • 00:45:21
    pull
  • 00:45:22
    okay
  • 00:45:24
    assign network to this pool
  • 00:45:26
    the network should be
  • 00:45:28
    this one one and two other ones theater
  • 00:45:30
    16 1.64 okay
  • 00:45:33
    she has 26 notation
  • 00:45:35
    so the network should be
  • 00:45:37
    192.18.1.64
  • 00:45:38
    [Music]
  • 00:45:43
    a subnet mask of two 255.255.255.192
  • 00:45:46
    [Music]
  • 00:45:51
    and you eat enter
  • 00:45:53
    default gateway now you assign the
  • 00:45:55
    default gateway default router the same
  • 00:45:58
    thing for the default router it will be
  • 00:46:02
    the ip address of the sub interface we
  • 00:46:05
    created
  • 00:46:06
    okay while implementing intervalon which
  • 00:46:09
    was touchscreen the ipaddress of this
  • 00:46:12
    interface was
  • 00:46:13
    0.65 okay
  • 00:46:16
    so it's a 12.168.1.65
  • 00:46:24
    and now dns server will also
  • 00:46:26
    [Music]
  • 00:46:29
    8.1.65
  • 00:46:31
    and domain name
  • 00:46:33
    will be let's say finance
  • 00:46:37
    dot com
  • 00:46:38
    and exit
  • 00:46:40
    we are done
  • 00:46:42
    for this subreddit and now these host
  • 00:46:45
    devices will be allocated i p address
  • 00:46:48
    automatically so let's go back to the
  • 00:46:51
    final
  • 00:46:53
    subnet
  • 00:46:54
    so let's go back to the last subnet
  • 00:46:56
    which is a
  • 00:46:58
    valentine css entry
  • 00:47:01
    cs and reception
  • 00:47:03
    which will create another pool which is
  • 00:47:05
    called ip dhcp
  • 00:47:10
    pool
  • 00:47:12
    let's say
  • 00:47:13
    css.com
  • 00:47:18
    okay sorry
  • 00:47:22
    no problem let's just go home
  • 00:47:25
    now network will send network to that
  • 00:47:27
    pool
  • 00:47:28
    which is this one okay
  • 00:47:31
    one and two
  • 00:47:33
    one two one eight dot one dot one two
  • 00:47:36
    eight
  • 00:47:37
    okay
  • 00:47:38
    subnet mask of 255.255.255.192
  • 00:47:44
    okay
  • 00:47:45
    and hit enter now default router will be
  • 00:47:49
    the ip address of that sub interface we
  • 00:47:51
    created while implementing interval and
  • 00:47:54
    routing which is dot three dot start amy
  • 00:47:57
    the appear address was dot one two nine
  • 00:48:02
    one two dot one sixty eight 68.1.129
  • 00:48:08
    dns
  • 00:48:12
    192.168.1.129
  • 00:48:19
    domain name
  • 00:48:21
    css.com
  • 00:48:25
    exit
  • 00:48:27
    do right
  • 00:48:29
    guys we are done configuring everything
  • 00:48:33
    as per the requirement okay
  • 00:48:36
    so basically what is remaining is to
  • 00:48:38
    test communication devices in all
  • 00:48:40
    departments are required to communicate
  • 00:48:42
    with each other that's to test
  • 00:48:44
    communication the first thing that i
  • 00:48:46
    will do
  • 00:48:47
    is to change the allocation ipa location
  • 00:48:50
    method to dtp i'll click on the pc
  • 00:48:53
    come to desktop i pay and you come to
  • 00:48:55
    dhcp give it time i hope it will pick up
  • 00:48:58
    as you can see
  • 00:49:00
    as you can see it's successful now for
  • 00:49:02
    the printer
  • 00:49:04
    config
  • 00:49:06
    then you come to
  • 00:49:07
    you come to first season x0
  • 00:49:10
    ip2 dhcp will pick up
  • 00:49:13
    as you can see dot 3.
  • 00:49:16
    and
  • 00:49:17
    for the access point let's just give
  • 00:49:20
    for the access point guys we'll play
  • 00:49:22
    some most devices at every department
  • 00:49:27
    so i will finish with this department
  • 00:49:28
    first now let's go back to the second
  • 00:49:32
    subnet
  • 00:49:33
    and do the same
  • 00:49:36
    and it will pick let's just give it time
  • 00:49:40
    click on the printer
  • 00:49:42
    and come to the facility zero
  • 00:49:44
    dcp give it time let me hover over it
  • 00:49:48
    it has taken six six okay
  • 00:49:51
    now for the last subnet
  • 00:49:53
    config
  • 00:49:55
    sorry
  • 00:49:57
    question is zero
  • 00:49:59
    as you can see it has it has picked
  • 00:50:00
    automatically now for the pc
  • 00:50:04
    it has a
  • 00:50:06
    config i mean dhcp
  • 00:50:09
    it has picked automatically okay and
  • 00:50:12
    printer
  • 00:50:14
    okay
  • 00:50:14
    all right guys so as we said
  • 00:50:19
    so guys in the problem
  • 00:50:22
    each department is required to have
  • 00:50:24
    wireless access network
  • 00:50:28
    each department is required to have
  • 00:50:30
    wireless network for the users so we
  • 00:50:32
    have access point here access point here
  • 00:50:34
    access point here so let's test them
  • 00:50:37
    i will place
  • 00:50:39
    things like let's say a smartphone here
  • 00:50:44
    and a laptop here
  • 00:50:47
    is laptop here
  • 00:50:49
    and a smartphone here
  • 00:50:50
    a smartphone here
  • 00:50:52
    and a laptop here
  • 00:50:55
    and try to connect them to the access
  • 00:50:57
    point so for example this one
  • 00:51:00
    the access point name was uh
  • 00:51:04
    it was a admin wi-fi
  • 00:51:07
    and the password was admin at one two
  • 00:51:09
    three so i'll go to smartphone and try
  • 00:51:11
    to connect to it
  • 00:51:15
    come to config
  • 00:51:18
    wireless zero
  • 00:51:19
    now
  • 00:51:20
    it's under ssd
  • 00:51:22
    press that word admin wi-fi and
  • 00:51:24
    authentication should be
  • 00:51:26
    admin
  • 00:51:28
    at one two three
  • 00:51:30
    and close this one i hope it will
  • 00:51:32
    connect just give it time
  • 00:51:34
    and it will check the appearance that it
  • 00:51:36
    has been assigned so let's go to the ip
  • 00:51:38
    address and check the appearance that it
  • 00:51:40
    has been assigned
  • 00:51:42
    go to desktop and check the dhcp delete
  • 00:51:46
    go back come back to static and again to
  • 00:51:49
    dcp
  • 00:51:51
    as you can see it has been assigned ip
  • 00:51:53
    address
  • 00:51:54
    in that network okay
  • 00:51:56
    so
  • 00:51:57
    finally
  • 00:51:58
    so also
  • 00:52:00
    in this department now let's connect
  • 00:52:02
    this laptop and to connect laptop guys
  • 00:52:05
    we have to insert a wireless model so
  • 00:52:09
    the first thing is to turn off the
  • 00:52:11
    laptop
  • 00:52:12
    and remove the existing model
  • 00:52:14
    as you can see now the part is empty and
  • 00:52:16
    drag this wpc 300 okay
  • 00:52:19
    press there turn it on again
  • 00:52:22
    now let's go back to the
  • 00:52:24
    laptop
  • 00:52:25
    and check the password
  • 00:52:27
    and let's check the password and this is
  • 00:52:29
    the name of this
  • 00:52:31
    wi-fi finance wi-fi finance at one two
  • 00:52:34
    three
  • 00:52:35
    four
  • 00:52:37
    for laptop you can desktop wireless pc
  • 00:52:40
    you come to pc wireless
  • 00:52:42
    and now you come to connect and refresh
  • 00:52:45
    just give it time
  • 00:52:48
    we have three
  • 00:52:49
    access points
  • 00:52:51
    css wi-fi admin wi-fi and finance wi-fi
  • 00:52:54
    and now we want to connect our finance
  • 00:52:55
    wi-fi
  • 00:52:56
    connect
  • 00:52:58
    the password is uh finance
  • 00:53:02
    at one two three
  • 00:53:04
    and you connect
  • 00:53:06
    close this
  • 00:53:07
    and close this one as you can see
  • 00:53:09
    it has connected successfully
  • 00:53:12
    okay
  • 00:53:14
    it has connected successfully
  • 00:53:17
    so finally let's go back to this
  • 00:53:19
    department also
  • 00:53:21
    and now i'll involve tablet and connect
  • 00:53:23
    the tablet on this side
  • 00:53:27
    so i'll click on the tablet
  • 00:53:30
    come back to
  • 00:53:35
    [Music]
  • 00:53:36
    come to
  • 00:53:37
    wireless0
  • 00:53:39
    and which wi-fi was this
  • 00:53:45
    css wi-fi cs wi-fi customer at one two
  • 00:53:48

    and plus
  • 00:54:02
    you want to see i appeared as that it
  • 00:54:04
    has been given
  • 00:54:07
    so pc let's go back to as you can see it
  • 00:54:10
    has been allocated ip address
  • 00:54:12
    dynamically okay
  • 00:54:15
    everything is working perfectly fine
  • 00:54:17
    guys and now what's remaining basically
  • 00:54:18
    is to test communication i will test
  • 00:54:21
    communication from this smartphone
  • 00:54:23
    to this pc and from this tablet
  • 00:54:26
    to this printer and finally from this
  • 00:54:28
    laptop
  • 00:54:29
    um
  • 00:54:30
    to
  • 00:54:31
    this print again
  • 00:54:33
    okay
  • 00:54:34
    or from this laptop to this smartphone
  • 00:54:36
    so let's start from this smartphone to
  • 00:54:39
    this pc the pc as
  • 00:54:42
    dot
  • 00:54:43
    131 okay
  • 00:54:45
    so i'll try to ping the 131
