The regular-expression regular-expression parameter is a regular expression. The regular expressions are the same ones supported for
BGP4 AS-path filters.
The address mask parameters specify a particular route. If you also use the optional longer-prefixes parameter, 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 , 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 can
also display route flap statistics for routes learned from a neighbor by entering the show ip bgp neighbor flap-statistics command.
The filter-list num parameter specifies one or more filters. Only routes that have been dampened and that match the specified filters are
displayed.
TABLE 101 show ip bgp flap-statistics output descriptions
This field Displays
Total number of flapping routes The total number of routes in the BGP4 route table that have changed
state and have been marked as flapping routes.
Status code 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 thus unusable.
• h - The route has a history of flapping and is unreachable now.
• * - The route has a history of flapping but is currently usable.
Network The destination network of the route.
From The neighbor that sent the route to this device.
Flaps The number of flaps (state changes) the route has experienced.
Since The amount of time since the first flap of this route.
Reuse The amount of time remaining until this route will be un-suppressed and
thus be usable again.
Path The AS-path information for the route.
You can display all dampened routes by entering the show ip bgp dampened-paths command.
Displaying the active route map configuration
You can view the active route map configuration (contained in the running configuration) without displaying the entire running
configuration by entering the following command at any level of the CLI.
device# show route-map
route-map permitnet4 permit 10
match ip address prefix-list plist1
route-map permitnet1 permit 1
match ip address prefix-list plist2
route-map setcomm permit 1
set community 1234:2345 no-export
route-map test111 permit 111
match address-filters 11
set community 11:12 no-export
route-map permit1122 permit 12
