Implementing BGP
Command or Action
Example:
RP/0/RSP0/CPU0:router(config)# show bgp flap-statistics
route-policy policy_A
Step 9 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 ]] { mask | /prefix-length }}
Example:
RP/0/RSP0/CPU0:router# show bgp flap-statistics 172.20.1.1
Step 10 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 ]] flap-statistics { ip-address [{ mask
| /prefix-length } [ longer-prefixes
Example:
RP/0/RSP0/CPU0:router# show bgp flap-statistics 172.20.1.1
longer-prefixes
Step 11 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
Example:
RP/0/RSP0/CPU0:router# clear bgp all all flap-statistics
Step 12
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 regexp
regular-expression
Example:
RP/0/RSP0/CPU0:router# clear bgp ipv4 unicast flap-statistics
regexp _1$
Step 13
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 ]] route-policy route-policy-name
