]]
flap-statistics regexp
regular-expression
Example:
RP/0/RP0/CPU0:router# show bgp flap-statistics
regexp _1$
Displays BGP flap statistics for all paths that match the
regular expression.
Step 8
show bgp [ipv4 {unicast | multicast |
labeled-unicast | all} | ipv6 {unicast |
multicast | all | labeled-unicast} | all
{unicast | multicast | all | labeled-unicast} |

]]
flap-statistics route-policy
route-policy-name
Example:
RP/0/RP0/CPU0:router(config)# show bgp
flap-statistics route-policy policy_A
Displays BGP flap statistics for the specified route policy.
Step 9
show bgp [ipv4 {unicast | multicast |
labeled-unicast | all} | ipv6 {unicast |
multicast | all | labeled-unicast} | all
{unicast | multicast | all | labeled-unicast} |

}}
Example:
RP/0/RP0/CPU0:router# show bgp flap-statistics
172.20.1.1
Displays BGP flap for the specified prefix.
Step 10
show bgp [ipv4 {unicast | multicast |

/prefix-length
} [longer-prefixes]]}
Example:
RP/0/RP0/CPU0:router# show bgp flap-statistics
172.20.1.1 longer-prefixes
Displays BGP flap statistics for more specific entries for the
specified IP address.
