timers
Use timers to configure RIP 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.
Views

Parameters
garbage-collect-value: Specifies the garbage-collect timer in the range of 1 to 3600 seconds.
suppress-value: Specifies the suppress timer in the range of 0 to 3600 seconds.
timeout-value: Specifies the timeout timer in the range of 1 to 3600 seconds.
update-value: Specifies the update timer in the range of 1 to 3600 seconds.
Usage guidelines
RIP uses the following timers:
• Update timer—Specifies the interval between routing updates.
• Timeout timer—Specifies the route aging time. If no update for a route is received before the timer
expires, RIP sets the metric of the route to 16.
• Suppress timer—Specifies how long a RIP route stays in suppressed state. When the metric of a
route becomes 16, the route enters the suppressed state. If RIP receives an update for the route from
the same neighbor and the route in the update has a metric less than 16, RIP uses the route to
replace the suppressed route.
• Garbage-collect timer—Specifies 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 a metric of 16. If no update is announced for that route before the garbage-collect timer expires,
RIP deletes the route from the routing table.
HP recommends not changing the default values of these timers.
The timer lengths must be consistent on all routers on the network.
The timeout timer must be greater than the update timer.
Examples
# Configure the update, timeout, suppress, and garbage-collect timers as 5, 15, 15, and 30 seconds.
