DAMPENING
Mode [BGP4+]
IPv6 Address Family Configuration
Usage
Route dampening minimizes the instability caused by route flapping. A penalty is
added for every flap in a flapping route. As soon as the total penalty reaches the
suppress
limit the advertisement of the route is suppressed. This penalty is
decayed according to the configured
half time
value. Once the penalty is lower
than the
reuse
limit, the route advertisement is un-suppressed.
The dampening information is purged from the router once the penalty becomes
less than half of the
reuse
limit.
