Monitoring and Maintaining BGP

You can remove all contents of a particular cache, table, or database. This might be necessary when the
contents of the particular structure have become or are suspected to be invalid.
You can display specific statistics, such as the contents of BGP routing tables, caches, and databases. You
can use the information to get resource utilization and solve network problems. You can also display information
about node reachability and discover the routing path your device's packets are taking through the network.
The table given below lists the privileged EXEC commands for clearing and displaying BGP. For explanations
of the display fields, see the Cisco IOS IP Command Reference, Volume 2 of 3: Routing Protocols, Release 12.4.
Table 15: IP BGP Clear and Show Commands
clear ip bgp address
Command or Action
show ip bgp flap-statistics [{regexp regexp} |
{filter-list list} | {address mask [longer-prefix]}]

Device# show pi bgp dampened-paths
clear ip bgp flap-statistics [{regexp regexp} |
{filter-list list} | {address mask [longer-prefix]}
Example:
Device# clear ip bgp flap-statistics
clear ip bgp dampening
Example:
Device# clear ip bgp dampening

Monitoring and Maintaining BGP
Purpose
(Optional) Monitors the flaps of all paths that
are flapping. The statistics are deleted when
the route is not suppressed and is stable.
(Optional) Displays the dampened routes,
including the time remaining before they are
suppressed.
(Optional) Clears BGP flap statistics to make
it less likely that a route will be dampened.
(Optional) Clears route dampening
information, and unsuppress the suppressed
routes.
(Optional) Saves your entries in the
configuration file.
Resets a particular BGP connection.
