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 (that is, 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.
