To clear the BGP4 message counter for a specific neighbor, enter a command such as the
following.
BigIron RX# clear ip bgp neighbor 10.0.0.1 traffic
To clear the BGP4 message counter for all neighbors within a peer group, enter a command such
as the following.
BigIron RX# clear ip bgp neighbor PeerGroup1 traffic
Syntax: clear ip bgp neighbor all | <ip-addr> | <peer-group-name> | <as-num> traffic
The all | <ip-addr> | <peer-group-name> | <as-num> specifies the neighbor. The <ip-addr>
parameter specifies a neighbor by its IP interface with the device. The <peer-group-name>
specifies all neighbors in a specific peer group. The <as-num> parameter specifies all neighbors
within the specified AS. The all parameter specifies all neighbors.
Clearing route flap dampening statistics
NOTE
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.
BigIron RX# clear ip bgp flap-statistics
Syntax: clear ip bgp flap-statistics [regular-expression <regular-expression> | <address> <mask>
| neighbor <ip-addr> ]
The parameters are the same as those for the show ip bgp flap-statistics command (except the
longer-prefixes option is not supported). Refer to
“Displaying route flap dampening statistics” on
page 848.
NOTE
The clear ip bgp damping command not only clears statistics but also un-suppresses the routes.
Refer to
“Displaying route flap dampening statistics” on page 848.
Removing route flap dampening
You can un-suppress routes by removing route flap dampening from the routes. The device allows
you to un-suppress all routes at once or un-suppress individual routes.
To un-suppress all the suppressed routes, enter the following command at the Privileged EXEC level
of the CLI.
BigIron RX# clear ip bgp damping
Syntax: clear ip bgp damping [ <ip-addr> <ip-mask> ]
The <ip-addr> parameter specifies a particular network.
The <ip-mask> parameter specifies the network’s mask.
To un-suppress a specific route, enter a command such as the following.
BigIron RX# clear ip bgp damping 209.157.22.0 255.255.255.0
This command un-suppresses only the routes for network 209.157.22.0/24.
