Here is an example of the information displayed by this command. Notice that most of the routes in this example
have type “B”, indicating that their source is BGP4.
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 <regular-expression> | <address> <mask>
[longer-prefixes] | neighbor <ip-addr> | filter-list <num>...]
The regular-expression <regular-expression> parameter is a regular expression. The regular expressions are
the same ones supported for BGP4 AS-path filters. See “Using Regular Expressions” on page 21-42.
The <address> <mask> parameter specifies a particular route. If you also use the optional 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 209.157.0.0 longer, then all routes with the prefix 209.157 or that
have a longer prefix (such as 209.157.22) are displayed.
The neighbor <ip-addr> parameter displays route flap dampening statistics only for routes learned from the
specified neighbor. You also can display route flap statistics for routes learned from a neighbor by entering the
following command: show ip bgp neighbor <ip-addr> flap-statistics.
The filter-list <num> parameter specifies one or more filters. Only the routes that have been dampened and that
match the specified filter(s) are displayed.
