Version 7.8.1.0 Introduced on the S-Series.Version 7.7.1.0 Introduced on the C-Series.UsageInformationTo determine a BGP session flap, both a route-down event and a subsequentroute-up event corresponding to a single route are considered. As a result, a flapevent is penalized only one time during the route-down event. The subsequentroute-up event corresponding to the same route is not considered as a flap and isnot penalized.The history paths that the show ip bgp command displays contain only the prefixand the next-hop information. The next-hop information shows the ip address ofthe neighbor. It does not show the actual next-hop details.The following describes the show ip bgp damp command shown in thefollowing example.Field DescriptionNetwork Displays the network ID to which the route is dampened.From Displays the IP address of the neighbor advertising thedampened route.Reuse Displays the hour:minutes:seconds until the dampenedroute is available.Path Lists all the ASs the dampened route passed through toreach the destination network.Example Dell#show ip bgp dampened-pathsBGP local RIB : Routes to be Added 0, Replaced 0, Withdrawn 0BGP local router ID is 192.168.11.5Status codes: s suppressed, S stale, d dampened, h history, *valid, > bestPath source: I - internal, a - aggregate, c - confed-external,r - redistributedn - network, D - denied, S - staleOrigin codes: i - IGP, e - EGP, ? - incompleteNetwork From Reuse Pathd 55.0.0.0/24 172.16.0.2 00:36:23 200Dell#show ip bgp detailDisplay BGP internal information for the IPv4 Unicast address family.S4810Syntax show ip bgp [ipv4 unicast] detailDefaults noneBorder Gateway Protocol 457
