Displaying BGP or MPLS VPNv4 information
6
The address / mask parameter specifies a particular route. When the user also uses 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, when the user specifies
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 as-path-filter num parameter specifies one or more filters. Only the routes that have been
dampened and that match the specified filter or filters are displayed.
The neighbor ip-addr parameter displays route flap dampening statistics only for routes learned
from the specified neighbor. The user 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 regular-expression regular-expression parameter is a regular expression. The regular
expressions are the same ones supported for BGP4 AS-path filters.
This display shows the following information.
TABLE 112 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.
The user also can display all the dampened routes by entering the following command:
show ip bgp dampened-paths.
Displaying VPNv4 route distinguisher information
In order to view the BGP VPNv4 information for routes that contain a specific route distinguisher,
enter the following command.
Brocade# show ip bgp vpnv4 rd 5:1 detail
