Displaying route flap dampening statistics
To display route dampening statistics or all the dampened routes, enter the following command at
any level of the CLI.
Syntax: show ip bgp flap-statistics [regular-expression

The regular-expression
expressions are the same ones supported for BGP4 AS-path filters. Refer to
The
longer-prefixes parameter, then all statistics for routes that match the specified route or have a
longer prefix than the specified route are displayed. For example, if you specify 10.157.0.0 longer,
then all routes with the prefix 10.157 or that have a longer prefix (such as 10.157.22) are
displayed.
The neighbor

neighbor by entering the following command: show ip bgp neighbor
