| 4.2.1 |  | Basic RIP v2 configuration |

RIP v2 is merely an enhancement of RIP v1 and not a separate protocol. The commands for manipulating timers, metrics, and, updates are exactly the same in both versions. After a brief look at configuring a RIP v2 process, the rest of this section concentrates on configuring the new extensions.

When RIP is first enabled on a Cisco router, the router listens for version 1 and 2 updates but sends only version 1. To take advantage of version 2 features, it is necessary to turn off version 1 support and enable version 2 updates with the following command:

1. Enable RIP v2 on the router using the following commands:

Router(config)#router rip
Router(config-router)#version 2
Router(config-router)#network network-number

By default, a RIP process configured on a Cisco router sends only RIP v1 messages but listens to both RIP v1 and RIP v2. This default is changed with the

version command. In this mode, the router sends and receives only RIP v2 messages.
- The router can also be configured to send and receive only RIP v1 messages:

Router(config)#router rip
Router(config-router)#version 1
Router(config-router)#network network-number

The default behavior can be restored by entering the command

no version in the config-router mode.
