update-value: Update timer time in seconds, in the range of 1 to 3600.
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 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.
HP does not recommend changing 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.
