Usage Information
To determine a BGP session ap, both a route-down event and a subsequent route-up event corresponding to a
single route are considered. As a result, a ap 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 ap and is not penalized.
The history paths that the show ip bgp command displays contain only the prex and the next-hop information.
The next-hop information shows the ip address of the neighbor. It does not show the actual next-hop details.
The following describes the show ip bgp damp command shown in the following example.
