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 to filter” on page336.
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 neighbors 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.
Table 7 2 lists the field definitions for the command output.
