Command Syntax
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.
1-45 half-life period in minutes, each time a route
is assigned a penalty, the penalty is decreased
by half after the half-life period in 5 second
intervals, with penalties being cumulative
1-20000 allows route to be reused if penalty for
flapping route falls below reuse value
1-20000 route suppresses when its penalty exceeds this
value
1-255 maximum suppression time in minutes
