■ route flap history—Status of route flap history for route paths
■ Prefix—The prefix for the IP address
■ Peer—IP address of the BGP peer
■ Status—Status of route dampening of the route path
■ Figure of Merit—A measure of the route's stability. Higher values indicate
more recent route flap activity or less stability.
■ Time until Reuse/Remove—Time until the route is either reused (if currently
suppressed) or its history entry is removed (if currently available)
■ Example
host1#show ip bgp dampened-paths
Local router ID 192.168.1.218, local AS 100
Route flap dampening is enabled
Decay half-life is 10 minutes while reachable, 20 minutes while
unreachable
Cuttoff threshold is 2000, reuse threshold is 750
Maximum hold-down time is 20 minutes
60 paths have active route flap histories (4560 bytes used)
11 paths are suppressed
