Hi John,
You may wish to investigate BGP Route Dampening:
IP Event Dampening is a feature based on the BGP route flap dampening code:
This will prevent BGP from even attempting to form a peering relationship.
The user guide and the parameters are very hard to understand.
Want to block a crashed router for 10 minutes:
dampening [half-life-period reuse-threshold] [suppress-threshold max-suppress [restart-penalty]]
How to work out the values:
