Configuring BGP Route Dampening
DETAILED STEPS
Command or Action
Step 1
configure
Step 2
router bgp as-number
Example:
RP/0/RSP0/CPU0:router(config)# router bgp 120
Step 3
address-family { ipv4 | ipv6 } unicast
Example:
RP/0/RSP0/CPU0:router(config-bgp)# address-family ipv4 unicast
Step 4
bgp dampening [ half-life [ reuse suppress max-suppress-time ] |
route-policy route-policy-name ]
Example:
RP/0/RSP0/CPU0:router(config-bgp-af)# bgp dampening 30 1500 10000
120
Step 5
commit
Step 6
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
Example:
RP/0/RSP0/CPU0:router# show bgp flap statistics
Step 7
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 regexp
regular-expression
Example:
RP/0/RSP0/CPU0:router# show bgp flap-statistics regexp _1$
Step 8
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 ]] route-policy route-policy-name
