Clearing the History
By clearing the dampening history, you are resetting all of the dampening information on all of the routes
back to zero, as if dampening had just been activated. Route flap counters are reset and any routes that
were suppressed due to route flapping violations are unsuppressed. Dampening information on the route
will start re-accumulating as soon as the command is entered and the statistics are cleared.
To clear the dampening history, enter the following command:
-> ip bgp dampening clear
