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 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.
