• Question 240:

  SIMULATION Lab SIM - RIP v2

  

  Correct Answer. Check the answer below
  Check the answer below

  ---

  Answer: Here are the answer with solution

  (1)

  Name the router: Router>enable Router#config terminal Router(config)#hostname Orlando

  (2)

  Enable-secret password (cisco10): Orlando(config)#enable secret cisco10

  (3)

  Set the console password toRouterPass: Orlando(config)#line console 0 Orlando(config-line)#password RouterPass Orlando(config-line)#login Orlando(config-line)#exit

  (4)

  Set the Telnet password toscan90: Orlando(config)#line vty 0 4 Orlando(config-line)#password scan90

  Orlando(config-line)#login Orlando(config-line)#exit

  (5)

  Configure Ethernet interface (on the right) of router Orlando:

  The subnet mask of the Ethernet network 209.165.201.0 is 27. From this subnet mask, we can find out the increment by converting it into binary form, that is /27 = 1111 1111.1111 1111.1111 1111.1110 0000. Pay more attention to the last bit

  1 because it tells us the increment, using the formula:

  Increment = 2place of the last bit 1 (starts counting from 0,from right to left), in this case increment = 25= 32.

  Therefore:

  Increment: 32

  Network address:209.165.201.0

  Broadcast address:209.165.201.31 (because 209.165.201.32 is the second subnetwork, so the previous IP 209.165.201.31 is the broadcast address of the first subnet).

  -> The second assignable host address of this subnetwork is209.165.201.2/27 Assign the second assignable host address to Fa0/0 interface of Orlando router:

  Orlando(config)#interface Fa0/0

  Orlando(config-if)#ip address 209.165.201.2 255.255.255.224 Orlando(config-if)#no shutdown

  Orlando(config-if)#exit

  (6)Configure Serial interface (on the left) of router Orlando:

  Using the same method to find out the increment of the Serial network:

  Serial network192.0.2.128/28:

  Increment:16 (/28 = 1111 1111.1111 1111.1111 1111.11110000) Network address:192.0.2.128 (because 8 * 16 = 128 so 192.0.2.128 is also the network address of this subnet)

  Broadcast address:192.0.2.143

  -> The last assignable host address in this subnet is192.0.2.142/28. Assign the last assignable host address to S0/0/0 interface of Orlando router:

  Orlando(config)#interface S0/0/0(or use interface S0/0 if not successful) Orlando(config-if)#ip address 192.0.2.142 255.255.255.240 Orlando(config-if)#no shutdown

  Orlando(config-if)#exit

  (7) Configure RIP v2 routing protocol:

  Orlando(config)#router rip

  Orlando(config-router)#version 2

  Orlando(config-router)#network 209.165.201.0

  Orlando(config-router)#network 192.0.2.128

  Orlando(config-router)#end

  (8)Save the configuration:

  Orlando#copy running-config startup-config

  Finally, you should use thepingcommand to verify all are working properly!
