Configuring RIPv2

February 9, 2011·

This guide will go over how to configure RIPv2 on Cisco routers. This guide follows a packet tracer activity that is posted at the end of this tutorial. RIPv2 configuration is pretty simple to understand with really only three required commands to use besides the network command which depends how many networks are connected to your router.

So following the packet tracer that is used with this tutorial the first step is to configure the hostname on the routers. Enter into the router and type the command enable to move into privilege EXEC mode, then type configure terminal to move into global configuration mode and type hostname then the name of the router. (this example is for R1)

Router>enable
Router#configure terminal
Router(config)#hostname R1

The next thing you need to do is to configure the interfaces on R1, R2, and R3 and remember to put a clock rate on the serial interfaces of R1 and R2 (s0/0/1) the clock rate the packet tracer will accept is 64000. The following are the outputs for each router.

R1’s Interface Setup:

R1(config)#interface fa0/0
R1(config-if)#ip address 192.168.1.62 255.255.255.192
R1(config-if)#no shut
R1(config-if)#exit
R1(config)#interface s0/0/0
R1(config-if)#ip add 192.168.1.193 255.255.255.252
R1(config-if)#clock rate 64000
R1(config-if)#no shut
R1(config-if)#exit
R1(config)#interface s0/0/1
R1(config-if)#ip add 192.168.1.197 255.255.255.252
R1(config-if)#clock rate 64000
R1(config-if)#no shut

R2’s Interface Setup:

R2(config)#interface fa0/0
R2(config-if)#ip add 192.168.1.126 255.255.255.192
R2(config-if)#no shut
R2(config-if)#exit
R2(config)#interface s0/0/0
R2(config-if)#ip add 192.168.1.194 255.255.255.252
R2(config-if)#no shut
R2(config-if)#exit
R2(config)#interface s0/0/1
R2(config-if)#ip add 192.168.1.201 255.255.255.252
R2(config-if)#clock rate 64000
R2(config-if)#no shut

R3’s Interface Setup:

R3(config)#interface fa0/0
R3(config-if)#ip add 192.168.1.190 255.255.255.192
R3(config-if)#no shut
R3(config-if)#exit
R3(config)#interface s0/0/0
R3(config-if)#ip add 192.168.1.202 255.255.255.252
R3(config-if)#no shut
R3(config-if)#exit 
R3(config)#interface s0/0/1 
R3(config-if)#ip add 192.168.1.198 255.255.255.252
R3(config-if)#no shut

The above commands have configured the interfaces for R1, R2, and R3. The next part of the step is to configure the PCs IP address and the default gateway. The default gateway is the router’s fast ethernet interface. For example PC-A’s default gateway would be 192.168.1.62. The next and final step is to configure RIPv2 on all the routers. You will use the same command for all the routers in this tutorial.

R1(config)#router rip
R1(config-router)#version 2
R1(config-router)#network 192.168.1.0

You may be wondering why you would use 192.168.1.0 network and not the different subnets connected to each router. This topology is using VLSM (variable-length subnet masking) so the router only needs the 192.168.1.0 network. You also should be at a 100 percent and able to ping every device.
