Example:
Step 10
RP/0/RP0/CPU0:router(config-bgp-nbrgrp)# exit
Places the router in neighbor configuration mode for BGP
routing and configures the neighbor IP address as a BGP
peer.

RP/0/RP0/CPU0:router(config-bgp)# neighbor
172.168.40.24
Step 11
(Optional) Specifies that the BGP neighbor inherit
configuration from the specified neighbor group.
use neighbor-group group-name

neighbor-group nbr-grp-A
Creates a neighbor and assigns a remote autonomous
system number to it.
remote-as as-number
Example:
Step 13
RP/0/RP0/CPU0:router(config-bgp-nbr)# remote-as

Configuring a Route Reflector for BGP
Perform this task to configure a route reflector for BGP.
All the neighbors configured with the route-reflector-clientcommand are members of the client group, and
the remaining iBGP peers are members of the nonclient group for the local route reflector.
Together, a route reflector and its clients form a cluster. A cluster of clients usually has a single route reflector.
In such instances, the cluster is identified by the software as the router ID of the route reflector. To increase
redundancy and avoid a single point of failure in the network, a cluster can have more than one route reflector.
