route-policy policy_A
Step 14
clear bgp [ ipv4 { unicast | multicast | labeled-unicast | all } | ipv6
unicast | all { unicast | multicast | all | labeled-unicast } | vpnv4
unicast [ rd rd-address ] | vrf { vrf-name | all } [ ipv4 { unicast |
labeled-unicast } | ipv6 unicast ]] flap-statistics network / mask-length
Example:
RP/0/RSP0/CPU0:router# clear bgp ipv4 unicast flap-statistics
192.168.40.0/24
Step 15
clear bgp [ ipv4 { unicast | multicast | labeled-unicast | all } | ipv6
unicast | all { unicast | multicast | all | labeled-unicast } | vpnv4
unicast [ rd rd-address ] | vrf { vrf-name | all } [ ipv4 { unicast |

Implementing BGP
Purpose

network.
Clears BGP flap statistics for routes
received from the specified neighbor.
Displays the dampened routes, including
the time remaining before they are
unsuppressed.
Clears route dampening information and
unsuppresses the suppressed routes.
Caution
Always use the clear bgp
dampening command for an
individual address-family. The
all option for address-families
with clear bgp dampening
should never be used during
normal functioning of the
system. For example, use
