Cisco ASR 9000 Series Routing Configuration Guide

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
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.
bgp cluster-id cluster-id
Example:
RP/0/RSP0/CPU0:router(config-bgp)# bgp
cluster-id 192.168.70.1
Step 3
Places the router in neighbor configuration mode for BGP
routing and configures the neighbor IP address as a BGP peer.
neighbor ip-address
Example:
RP/0/RSP0/CPU0:router(config-bgp)# neighbor
Step 4
172.168.40.24
Creates a neighbor and assigns a remote autonomous system
number to it.
remote-as as-number
Example:
RP/0/RSP0/CPU0:router(config-bgp-nbr)#
remote-as 2003
Step 5
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-nbr)#
address-family ipv4 unicast
Step 6

this command, use the CLI help (?).
Configures the router as a BGP route reflector and configures
the neighbor as its client.
