Displaying BGP4 information
27
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 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.
You also can display all the dampened routes by entering the following command.
show ip bgp dampened-paths.
Displaying the active route map configuration
You can view the device’s active route map configuration (contained in the running configuration)
without displaying the entire running configuration.
To display the device’s active route map configuration, enter the following command at any level of
the CLI.
BigIron RX# 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
TABLE 144 Route flap dampening statistics
This field... Displays...
Total number of flapping routes The total number of routes in the device’s BGP4 route table that have
changed state and thus have been marked as flapping 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’s 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 the 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 Shows the AS-path information for the route.
