Helping You Pass Your CCNA Exams

New CCNA RIP v2 Configuration Simulation Exam.

 This is an Updated real CCNA exam question (Sept.2013). You might see a different IP addressing.
As usual, take time to read through the question so as to clearly understand what Cisco want you to do.

Note: This RIP v2 LAB are used for demonstration only, you will see different IP addressing, VLAN configuration and Port allocation in the real CCNA exam. But it all works the same way if you could just grasp the technique.

I suggest you use packet tracer for practice.

To configure the router (R2-RC) 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)

Central Florida Widgets recently installed a new router in their office. Complete the network installation by performing the initial router configurations and configuring RIPV2 routing using the router command line interface (CLI) on the R2-RC.

Router configuration:

Name of the router is R2-RC
Enable-secret password is cisco1
The password to access user EXEC mode using the console is cisco2
The password to allow telnet access to the router is cisco3

IPV4 addresses must be configured as follows:

Ethernet network router has last assignable host address in subnet

Serial network is router has last assignable host address in the subnet. Interfaces should be enabled.
Router protocol is RIPV2    



1. Configure router name:

Router#configure terminal
Router(config)#hostname R2-RC

2. Configure secret password:

R2-RC(config)# enable secret cisco1

3) Configure console Password:

R2-RC(config)#line console 0
R2-RC(config-line)#password cisco2

4) Configure Telnet password:

R2-RC(config)#line vty 0 4
R2-RC(config-line)#password cisco3

5) Assign IP address for Ethernet interface(Fa0/0):

I will advise you to try and know or cram this table below; you might be given an opportunity to write it down before the exam:

Bit Value                    128     64     32     16     8     4         2        1

BitsBorrowed              1       2        3       4      5      6        7       8

Subnetmask              128    192    224  240   248   252     254   255

SubnetPrefix /CIDR   /25    /26   /27     /28   /29    /30

Normal 0 false false false EN-GB X-NONE X-NONE MicrosoftInternetExplorer4
The Ethernet network looking at the table above, you can see that the /27 has a bit value of 32 (increment) and mask should be 224 or /27

 That means:

Network address:

Subnet mask:
Broadcast address: (because 128 + 32 - 1 = 159)

Therefore, according to the question; the last assignable host address in this subnet should be: Assign it to fa0/0 using these commands:

R2-RC(config)# interface fa0/0
R2-RC(config-if)#ip address
R2-RC(config-if)#no shutdown

6) Assign IP address for Serial interface(S0/0/0): (follow the same above)

Serial network /28

 Looking at the table above, you can see that the /28 has a bit value of 16 (increment) and mask should be 240 or /28

 That means:

Serial network

Subnet mask:

Broadcast address: (because 16 + 16 - 1 = 31)

According to the question the last assignable host address in this subnet is Assign it to s0/0/0 interface using the following command:

R2-RC(config)# interface s0/0/0
R2-RC(config-if)#ip address
R2-RC(config-if)#no shutdown

7) Configure RIP v2 routing protocol using the following command:

R2-RC(config)#router rip
R2-RC(config-router)#version 2
R2-RC#copy running-configstartup-config 
(don’t forget this bit)
