timers
Use timers to configure RIPng timers.
Use undo timers to restore the default.
Syntax
timers { garbage-collect garbage-collect-value | suppress suppress-value | timeout timeout-value | update update-value } *
undo timers { garbage-collect | suppress | timeout | update } *
Default
The garbage-collect timer is 120 seconds, the suppress timer is 120 seconds, the timeout timer is 180 seconds, and the update timer is 30 seconds.

Parameters
garbage-collect-value: Sets the garbage-collect timer in the range of 1 to 86400 seconds.
suppress-value: Sets the suppress timer in the range of 0 to 86400 seconds.
timeout-value: Sets the timeout timer in the range of 1 to 86400 seconds.
update-value: Sets the update timer in the range of 1 to 86400 seconds.
Usage guidelines
RIPng has the following timers:
Update timer—Interval between update messages.
Timeout timer—Route aging time. If no update for a route is received before the timer expires, RIPng sets the metric of the route to 16.
Suppress timer—How long a RIPng route stays in suppressed state. When the metric of a route becomes 16, the route enters the suppressed state. If RIPng receives an update for the route from the same neighbor and the route in the update has a metric less than 16, RIPng uses the route to replace the suppressed route.
Garbage-collect timer—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, RIPng advertises the route with a metric of 16. If no update is announced for that route before the garbage-collect timer expires, RIPng deletes the route from the routing table.
As a best practice, do not change the default values of these timers.
The timer lengths must be kept consistent on all routers in the network.
Examples
# Configure the update, timeout, suppress, and garbage-collect timers as 5 seconds, 15 seconds, 15 seconds, and 30 seconds.
