Configuring RIPv2

Configuring RIPv2 is a pretty straightforward process. Only three steps are required:

1. enabling RIP by using the router rip global configuration command
2. instructing the router to use RIPv2 by typing the version 2 command
3. telling RIP which networks to advertise by using one or more network commands.

The first two commands are easy to comprehend, but the last command requires a little bit more thought. With the network command you specify which interfaces will participate in the routing process. This command takes a classful network as a parameter and enables RIP on the corresponding interfaces.Let’s configure our sample network to use RIP.

Router R1 and R2 have directly connected subnets. We want to include these subnets in the RIP routing process. To do that, we first need to enable RIP on both routers and then advertise these subnets using the network command.

On router R1, in the global configuration mode, enter the router rip command to enable RIP. In the RIP configuration mode, change the version of the protocol to 2 by using the version 2 command. Next, use the network command to include the Fa0/1 interface on the router R1 in the routing process. Remember, the network command takes a classful network number as a parameter, so in this case every interface that has an IP address that begins with 10 will be included in the RIP process (IP addresses that begins with 10 are, by default, the class A addresses and have the default subnet mask of For instance, if another interface on the router had the IP address of it would also be included in the routing process with the network command. You also need to include the link between the two routers in the RIP routing process. This is done by adding another network statement, network

So, the configuration on R1 should look like this:

router1 rip configuration

The configuration on R2 looks similar, but with different network number for the directly connected subnet:

router2 rip configuration

You can verify that router R1 have a route to the R2’s directly connected subnet by typing the show ip route command:

show ip route rip

The legend lists R for all RIP routes in the routing table. Also note that the administrative distance of 120 is shown, together with the metric of 1.

Prerequisites for 200-301

200-301 is a single exam, consisting of about 120 questions. It covers a wide range of topics, such as routing and switching, security, wireless networking, and even some programming concepts. As with other Cisco certifications, you can take it at any of the Pearson VUE certification centers.

The recommended training program that can be taken at a Cisco academy is called Implementing and Administering Cisco Solutions (CCNA). The successful completion of a training course will get you a training badge.
