Command mode: RIP configuration mode
Usage Guide: The system advertises RIP update packets every 30 seconds by default. If
no update packet form a route is received after 180 seconds, this route is considered to be
invalid. However, the route will be kept in the route table for another 120 seconds, and will
be deleted after that. It should be noted in adjusting RIP timeout timers that the time to
declare invalid route should be at least greater than RIP update time, holddown time
should also be greater than RIP update interval and must be integer multiples of the RIP
update interval.
Example: Set the RIP route table update time to 20 seconds, time to declare invalid to 80
seconds, and time to delete entry to 60 seconds.
