Parameters
update-timer
: Length of the Period Update timer in seconds, in the range of 1 to 3600.
timeout-timer
: Length of the Timeout timer in seconds, in the range of 1 to 3600.
Description
Use the timers command to modify the lengths of the three RIP timers: Period Update, Timeout, and
Garbage-collection (which is usually set to a length four times that of the Period Update timer).
Garbage-collection (which is usually set to a length four times that of the Period Update timer).
Use the undo timers command to restore the default settings.
By default, the lengths of the Period Update, Timeout, and Garbage-collection timers are 30 seconds,
180 seconds, and 120 seconds, respectively.
180 seconds, and 120 seconds, respectively.
Generally, it is regarded that the value of the Garbage-collection timer is fixed at four times that of the
Period Update timer. Adjusting the Period Update timer will affect the Garbage-collection timer.

The modification of RIP timers is validated immediately.
As specified in RFC 1058, RIP is controlled by the above three timers:
z
The update timer defines the interval between routing updates.
z
The timeout timer defines the route aging time. If no routing update related to a route is received
within the aging time, the metric of the route is set to 16 in the routing table.
within the aging time, the metric of the route is set to 16 in the routing table.
z
The garbage-collect timer defines the interval from when the metric of a route becomes 16 to when
it is deleted from the routing table. During the Garbage-Collect timer length, RIP advertises the
route with the routing metric set to 16. If no routing update is announced for that route after the
Garbage-Collect timer expires, the route will be deleted from the routing table.
