Cisco ASR 9000 Series Configuration Guide

PurposeCommand or Action
Example:
RP/0/RSP0/CPU0:router# clear bgp ipv4 unicast flap-statistics
route-policy policy_A
Clears BGP flap statistics for the specified
network.
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
Step 14
Example:
RP/0/RSP0/CPU0:router# clear bgp ipv4 unicast flap-statistics
192.168.40.0/24
Clears BGP flap statistics for routes
received from the specified neighbor.
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 ip-address / mask-length
Step 15
Example:
RP/0/RSP0/CPU0:router# clear bgp ipv4 unicast flap-statistics
172.20.1.1
Displays the dampened routes, including
the time remaining before they are
unsuppressed.
show 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 ]] dampened-paths
Step 16
Example:
RP/0/RSP0/CPU0:router# show bgp dampened-paths
Clears route dampening information and
unsuppresses the suppressed routes.
clear bgp [ ipv4 { unicast | multicast | labeled-unicast | all } | ipv6
unicast | all { unicast | multicast | all | labeled-unicast } | vpnv4
Step 17
unicast [ rd rd-address ] | vrf { vrf-name | all } [ ipv4 { unicast |
labeled-unicast } | ipv6 unicast ]] dampening ip-address / mask-length
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 clear
bgp ipv4 unicast dampening
prefix x.x.x./y
Caution
Example:
RP/0/RSP0/CPU0:router# clear bgp dampening
