DETAILED STEPS
Command or Action Purpose
Step 1
configure
Example:
RP/0/RP0/CPU0:router# configure
Enters global configuration mode.
Step 2
router bgp as-number
Example:
RP/0/RP0/CPU0:router(config)# router bgp 120
Enters BGP configuration mode, allowing you to configure
the BGP routing process.
Step 3
address-family {ipv4 unicast | ipv4 multicast |
| ipv6 unicast | ipv6 multicast}
Example:
RP/0/RP0/CPU0:router(config-bgp)#
address-family ipv4 unicast
Enters address family configuration mode for the specified
address family.
Step 4
bgp dampening [half-life [reuse suppress
max-suppress-time] | route-policy
route-policy-name]
Example:
RP/0/RP0/CPU0:router(config-bgp-af)# bgp
dampening 30 1500 10000 120
Configures BGP dampening for the specified address
family.
