Command Usage
•The update timer sets the rate at which updates are sent. This is the
fundamental timer used to control all basic RIP processes.
•The timeout timer is the time after which there have been no update
messages that a route is declared dead. The route is marked inaccessible
(i.e., the metric set to infinite) and advertised as unreachable. However,
packets are still forwarded on this route.
• After the timeout interval expires, the router waits for an interval
specified by the garbage-collection timer before removing this entry from
the routing table. This timer allows neighbors to become aware of an
invalid route prior to purging it.
• Setting the update timer to a short interval can cause the router to
spend an excessive amount of time processing updates.
• These timers must be set to the same values for all routers in the
network.
Example
This example sets the update timer to 40 seconds. The timeout timer is
subsequently set to 240 seconds, and the garbage-collection timer to 160
seconds.
network
Use this command to specify the network interfaces that will be included
in the RIP routing process. Use the no form to remove an entry.
