Подготовка к экзамену CCNA. Практические задания.



Central Florida Widgets recently installed a new router in their Apopka office. Complete the network installation by performing the initial router configurations and configuring RIPv2 routing using the router command line interface (CLI) on the Apopka router.

Configure the router per the following requirements:

Name of the router is Apopka
Enable-secret password is cisco10
The password to access user EXEC mode using the console is RouterPass
The password to allow telnet access to the router is scan90

IPv4 addresses must be configured as follows:
Ethernet network – router has second assignable host address in subnet.
Serial network is – router has last assignable host address in the subnet. Interfaces should be enabled.
Routing protocol is RIPv2.

(Notice: In the real exam the name, passwords, IP addresses and the positions of the assignable host addresses might be different)


To configure the router (Apopka) click on the console host icon that is connected to a router by a serial console cable (shown in the diagram as a dashed black line).

Each of the windows can be minimized by clicking on the [-]. You can also reposition a window by dragging it by the title bar.
The “Tab” key and most commands that use the “Control” or “Escape” keys are not supported and are not necessary to complete this simulation. The help command does not display all commands of the help system.

Answer and Explanation:

1) Name the router:

Router#config terminal
Router(config)#hostname Apopka

2) Enable-secret password (cisco10):

Apopka(config)#enable secret cisco10

3) Set the console password to RouterPass:

Apopka(config)#line console 0
Apopka(config-line)#password RouterPass

4) Set the Telnet password to scan90:

Apopka(config)#line vty 0 4
Apopka(config-line)#password scan90

5) Configure Ethernet interface (on the right) of router Apopka:

The subnet mask of the Ethernet network 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:
Broadcast address: (because is the second subnetwork, so the previous IP – – is the broadcast address of the first subnet).

-> The second assignable host address of this subnetwork is

Assign the second assignable host address to Fa0/0 interface of Apopka router:

Apopka(config)#interface Fa0/0
Apopka(config-if)#ip address
Apopka(config-if)#no shutdown

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

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

Serial network

Increment: 16 (/28 = 1111 1111.1111 1111.1111 1111.1111 0000)
Network address: (because 8 * 16 = 128 so is also the network address of this subnet)
Broadcast address:

-> The last assignable host address in this subnet is

Assign the last assignable host address to S0/0/0 interface of Apopka router:

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

7) Configure RIP v2 routing protocol:

Apopka(config)#router rip
Apopka(config-router)#version 2

Save the configuration:

Apopka#copy running-config startup-config

Finally, you should use the ping command to verify all are working properly!

Всем удачи!
