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.
