Usage
Information
To determine a BGP session flap, both a route-down event and a subsequent
route-up event corresponding to a single route are considered. As a result, a flap
event is penalized only one time during the route-down event. The subsequent
route-up event corresponding to the same route is not considered as a flap and is
not penalized.
The history paths that the show ip bgp command displays contain only the prefix

the neighbor. It does not show the actual next-hop details.
