Configuring RIP Timers

You can configure various timers for RIP.

RIP routes expire when either a route timeout limit is met or a route metric reaches infinity, and the route is no longer valid. However, the expired route is retained in the routing table for a time period so that neighbors can be notified that the route has been dropped. This time period is set by configuring the hold-down timer. Upon expiration of the hold-down timer, the route is removed from the routing table.

To configure the hold-down timer for RIP, include the holddown statement:




holddown seconds;

seconds can be a value from 10 through 180. The default value is 120 seconds.

For a list of hierarchy levels at which you can configure this statement, see the statement summary section for this statement.

You can set a route timeout interval. If a route is not refreshed after being installed into the routing table by the specified time interval, the route is removed from the routing table.

To configure the route timeout for RIP, include the route-timeout statement:




route-timeout seconds;

seconds can be a value from 30 through 360. The default value is 180 seconds.

For a list of hierarchy levels at which you can configure this statement, see the statement summary section for this statement.

You can set an update time interval to periodically send out routes learned by RIP to neighbors.

To configure the update time interval, include the update-interval statement:




update-interval seconds;

seconds can be a value from 10 through 60. The default value is 30 seconds.
