How to configure Routing information protocol RIP routing
In this article I will demonstrate an example of Rip Routing configurations. We will use four different series router so you can get familiar with all different platform covered in CCNA exam. Create a topology as shown in figure.
IP RIP comes in two different versions: 1 and 2. Version 1 is a distance vector protocol and is defined in RFC 1058. Version 2 is a hybrid protocol and is defined in RFCs 1721 and 1722. The CCNA exam now primarily focuses on version 2. There are no major differences between RIPv1 or RIPv2 so far configurations concern. To read more about differences between RIPv1 or RIPv2 or know about the characteristics read our pervious article about RIP.

To configure any router double click on it and select CLI. To configure this topology use this step by step guide.

If you get replay then you have successfully configured rip routing but if you did not get replay double check this configuration and try to troubleshoot.

|
