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
# Set the update, timeout, suppress, and garbage-collect timers to 5 seconds, 15 seconds, 15
seconds, and 30 seconds.
