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
