— RIP command: timers basic update timeout garbage

RIP protocol has several timers. User can configure those timers' values by timers basic command.

The default settings for the timers are as follows:

• The update timer is 30 seconds. Every update timer seconds, the RIP process is awakened to send an unsolicited Response message containing the complete routing table to all neighboring RIP routers.
• The timeout timer is 180 seconds. Upon expiration of the timeout, the route is no longer valid; however, it is retained in the routing table for a short time so that neighbors can be notified that the route has been dropped.
• The garbage collect timer is 120 seconds. Upon expiration of the garbage-collection timer, the route is finally removed from the routing table.

The timers basic command allows the the default values of the timers listed above to be changed.

— RIP command: no timers basic

The no timers basic command will reset the timers to the default settings listed above.
