Bgp Dampening - Motorola BSR 64000 Reference Manual

BSR 64000 Command Reference Guide

bgp dampening

The bgp dampening command enables BGP route dampening. The no bgp
dampening command to sets the default values or disables this function.
Note: The penalty is halved after the half-life period when a route is flapping.
The router configured for damping (dampening) assigns a penalty to a route
when a route flaps. Penalties are cumulative and are stored in the BGP
routing table. A flapping route is suppressed when its penalty exceeds the
suppress limit. A suppressed route is reused when its decayed penalty falls
below the reuse limit.
