Displaying and clearing route flap dampening statistics

The software provides many options for displaying and clearing route flap statistics. To display the

Syntax: show ip bgp flap-statistics [regular-expression <regular-expression> | <address> <mask>
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
expressions"
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 neighbors <ip-addr> flap-statistics.
