Configure the Hold-Down Timer

When RIPng detects a route with a high metric associated, the router waits for a period of time before making any updates into the routing table. This minimizes the effects of route flapping to the routing table. The period of time that RIPng waits is the hold-down timer.

To configure the hold-down timer for RIPng, include the holddown statement:

holddown seconds; 

seconds can be a value from 10 through 180. The default value is 180 seconds.
