◆ 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.
E XAMPLE
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.
