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 it
being purged by this device.
◆
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.
