timeout-value: Timeout timer time in seconds, in the range of 1 to 3,600.
update-value: Update timer time in seconds, in the range of 1 to 3,600.
Description Use the
timers command to configure RIP timers. By adjusting RIP timers, you can
improve network performance.
Use the
undo timers command to restore the default.
By default, the garbage-collect timer is 120 seconds, the suppress timer 120
seconds, the timeout timer 180 seconds, and the update timer 30 seconds.
RIP is controlled by the above four timers.
■ The update timer defines the interval between routing updates.
■ The timeout timer defines the route aging time. If no routing update related to
a route is received after the aging time, the metric of the route is set to 16 in
the routing table.
■ The suppress timer defines how long a RIP route stays in the suppressed state.
When the metric of a route is 16, the route enters the suppressed state. In the
suppressed state, only routes which come from the same neighbor and whose
metric is less than 16 will be received by the router to replace unreachable
routes.
■ 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.
Note that:
■ Generally, you are not recommended to change the default values of these
timers.
■ The time lengths of these timers must be kept consistent on all routers and
access servers in the network.
Examples # Specifies the update, timeout, suppress, and garbage-collect timers as 5, 15, 15
and 30 respectively.
