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.
Table 12-5 defines the information displayed in Figure 12-11.
