BGP Route Reflector: Example

address-family ipv4 unicast
In a BGP speaker in autonomous system 6003, the peers from autonomous systems 6001 and 6002 are
configured as special eBGP peers. Peer 192 .168 .200.200 is a normal eBGP peer from autonomous system
701.

The following is a part of the configuration from the BGP speaker 192 .168 .200.205 from autonomous system
701 in the same example. Neighbor 171.16 .232.56 is configured as a normal eBGP speaker from autonomous
system 666. The internal division of the autonomous system into multiple autonomous systems is not known
to the peers external to the confederation.

The following example shows how to use an address family to configure internal BGP peer 10.1.1.1 as a route
reflector client for both unicast and multicast prefixes:
