DETAILED STEPS
Step 1
configure
Step 2
router bgp as-number
Example:
RP/0/RP0/CPU0:router(config)# router bgp 120
Specifies the autonomous system number and enters the BGP configuration mode, allowing you to configure the BGP
routing process.
Step 3 bgp cluster-id cluster-id
Example:
RP/0/RP0/CPU0:router(config-bgp)# bgp cluster-id 192.168.70.1
Configures the local router as one of the route reflectors serving the cluster. It is configured with a specified cluster ID
to identify the cluster.
Step 4
neighbor ip-address
Example:
RP/0/RP0/CPU0:router(config-bgp)# neighbor 172.168.40.24
Places the router in neighbor configuration mode for BGP routing and configures the neighbor IP address as a BGP peer.
Step 5 remote-as as-number
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr)# remote-as 2003
Creates a neighbor and assigns a remote autonomous system number to it.
Step 6 address-family { ipv4 | ipv6 } unicast
Example:
RP/0/RP0/CPU0:router(config-nbr)# address-family ipv4 unicast
Specifies either an IPv4 or IPv6 address family unicast and enters address family configuration submode.
