Displaying BGP4 information
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. Refer to
“Using regular
expressions” on page 705.
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 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 <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 filters are displayed.
This display shows the following information.
