To configure RIP, enable RIP routing for a network and optionally configure other parameters.
Beginning in privileged EXEC mode, follow these steps to enable and configure RIP:
Command
Step 1
Router# configure terminal
Step 2
Router(config)# ip routing
Step 3
Router(config)# router rip
Step 4
Router(config-router)# network
network number
Step 5
Router(config-router)# neighbor

Step 6
Router(config-router)# offset list

Default Setting
None defined.
None specified.
Disabled.
0 milliseconds.
Update: 30 seconds.
Invalid: 180 seconds.
Hold-down: 180 seconds.
Flush: 240 seconds.
Enabled.
Receives RIP Version 1 and Version 2 packets;
sends Version 1 packets.
Purpose
Enters global configuration mode.
Enables IP routing. (Required only if IP routing is disabled.)
Enables a RIP routing process, and enters router configuration mode.
Associates a network with a RIP routing process. You can specify
multiple network commands. RIP routing updates are sent and received
through interfaces only on these networks.
(Optional) Defines a neighboring router with which to exchange routing
information. This step allows routing updates from RIP (normally a
broadcast protocol) to reach nonbroadcast networks.
(Optional) Applies an offset list to routing metrics to increase incoming

and outgoing metrics to routes learned through RIP. You can limit the
]
offset list with an access list or an interface.
(Optional) Adjusts routing protocol timers. Valid ranges for all timers are
0 to 4294967295 seconds.
•
update—The time (in seconds) between sending of routing updates.
The default is 30 seconds.
•
invalid—The timer interval (in seconds) after which a route is
declared invalid. The default is 180 seconds.
holddown—The time (in seconds) that must pass before a route is
•
removed from the routing table. The default is 180 seconds.
•
flush—The amount of time (in seconds) for which routing updates
are postponed. The default is 240 seconds.
