IPv6 Border Gateway Protocol (IPv6 BGP) | 801
Usage
Information
When a BGP cluster contains only one route reflector, the cluster ID is the route
reflector’s router ID. For redundancy, a BGP cluster may contain two or more route
reflectors and you assign a cluster ID with the bgp cluster-id command. Without a
cluster ID, the route reflector cannot recognize route updates from the other route
reflectors within the cluster.
The default format for displaying the cluster-id is dotted decimal, but if you enter the
cluster-id as an integer, it will be displayed as an integer.

Information
The autonomous systems configured in this command are visible to the EBGP
neighbors. Each autonomous system is fully meshed and contains a few connections
to other autonomous systems. The next hop, MED, and local preference information
is preserved throughout the confederation.
FTOS accepts confederation EBGP peers without a LOCAL_PREF attribute. The
software sends AS_CONFED_SET and accepts AS_CONFED_SET and
AS_CONF_SEQ.
bgp client-to-client reflection Enable route reflection between route reflector and clients.
neighbor route-reflector-client Configure a route reflector and clients.
