DETAILED STEPS
PurposeCommand or Action
configure
Step 1
Specifies the autonomous system number and enters
the BGP configuration mode, allowing you to
configure the BGP routing process.
router bgp as-number
Example:
RP/0/RSP0/CPU0:router(config)# router bgp 120
Step 2
Enables BGP routing for a particular VRF on the PE
router.
vrf vrf-name
Example:
RP/0/RSP0/CPU0:router(config-bgp)# vrf vrf_a
Step 3
Specifies either an IPv4 or IPv6 address family unicast
and enters address family configuration submode.
address-family { ipv4 | ipv6 } unicast
Example:
RP/0/RSP0/CPU0:router(config-vrf)# address-family ipv4
unicast
