The regular-expression regular-expression parameter is a regular expression. Regular expressions are the same ones supported for
BGP4 AS-path lters.
The address mask parameters specify a particular route. If you also use the optional longer-prexes parameter, all statistics for routes
that match the specied route or have a longer prex than the specied route are displayed. For example, if you specify 10.157.0.0
longer , all routes with the prex 10.157. or longer (such as 10.157.22.) are displayed.
The neighborip-addr parameter displays route ap dampening statistics only for routes learned from the specied neighbor. You also
can display route ap statistics for routes learned from a neighbor by entering the following command: show ip bgp neighbor ap-
statistics .
The as-path-lter num parameter species one or more lters. Only the routes that have been dampened and that match the specied
lter or lters are displayed.
TABLE 91 show ip bgp
ap-statistics output descriptions
This eld Displays
Total number of apping routes The total number of routes in the BGP4 route table that have changed
state and have been marked as apping routes.
Status code Indicates the dampening status of the route, which can be one of the
following:
• > - This is the best route among those in the BGP4 route table
to the route destination.
• d - This route is currently dampened, and unusable.
• h - The route has a history of apping and is unreachable now.
• * - The route has a history of apping but is currently usable.
Network The destination network of the route.
From The neighbor that sent the route to the device.
Flaps The number of aps the route has experienced.
Since The amount of time since the rst ap of this route.
Reuse The amount of time remaining until this route will be un-suppressed and
can be used again.
Path Shows the AS-path information for the route.
You also can display all dampened routes by entering the show ip bgp dampened-paths command.
Clearing route
ap dampening statistics
Clearing the dampening statistics for a route does not change the dampening status of the route. To clear all the route dampening
statistics, enter the following command at any level of the CLI.
device# clear ip bgp flap-statistics
Syntax: clear ip bgp ap-statistics [ regular-expression regular-expression | address mask | neighbor ip-addr ]
The parameters are the same as those for the show ip bgp ap-statistics command (except the longer-prexes option is not
supported).
NOTE
The clear ip bgp dampening command not only clears statistics but also un-suppresses the routes.
