Configuring the RIPng Timers
RIPng has three timers: Update timer, Age timer and Garbage-collect timer. If the three RIPng timers are configured improperly, routes become unstable.
Context
Route flapping occurs if the values of the four RIPng timers are set improperly. The relationship between the values is as follows: update < age, update < garbage-collect. For example, if the update time is longer than the aging time, and a RIPng route changes within the update time, the router cannot inform its neighbors of the change on time.
By default, the Update timer is 30s; the Age timer is 180s; the Garbage-collect timer is 120s.
