Configuring Routing Information Protocol

RIP Configuration Task List

To adjust the timers, use the following command in router configuration mode:

Command	Purpose
Router(config-router)# timers basic update invalid	Adjusts routing protocol timers.
holddown flush [sleeptime]

See the “Address Family Timers Example” section at the end of this chapter for examples of adjusting timers for an address family (VRF).

Specifying a RIP Version

The Cisco implementation of RIP Version 2 supports authentication, key management, route summarization, CIDR, and VLSMs. Key management and VLSM are described in the chapter “Configuring IP Routing Protocol-Independent Features.”

By default, the software receives RIP Version 1 and Version 2 packets, but sends only Version 1 packets. You can configure the software to receive and send only Version 1 packets. Alternatively, you can configure the software to receive and send only Version 2 packets. To configure the software to send and receive packets from only one version, use the following command in router configuration mode:

Command	Purpose
Router(config-router)# version {1 2}	Configures the software to receive and send only RIP
	Version 1 or only RIP Version 2 packets.

The preceding task controls the default behavior of RIP. You can override that behavior by configuring a particular interface to behave differently. To control which RIP version an interface sends, use the following commands in interface configuration mode, as needed:

:

Command		Purpose
Router(config-if)#ip rip send version 1		Configures an interface to send only RIP Version 1 packets.
Router(config-if)#ip rip send version 2		Configures an interface to send only RIP Version 2 packets.
Router(config-if)#ip rip send version 1	2	Configures an interface to send RIP Version 1 and Version 2
		packets.

Similarly, to control how packets received from an interface are processed, use the following commands in interface configuration mode, as needed:

Command		Purpose
Router(config-if)#ip rip receive version 1		Configures an interface to accept only RIP Version 1 packets.
Router(config-if)#ip rip receive version 2		Configures an interface to accept only RIP Version 2 packets.
Router(config-if)#ip rip receive version 1	2	Configures an interface to accept either RIP Version 1 or 2
		packets.
