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. 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 is displayed as an integer.

Usage
Information
You must configure your system to accept 4-byte formats before entering a 4-byte
AS number. All the routers in the Confederation must be 4– or 2-byte identified
routers. You cannot mix them.
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.
Dell Networking OS accepts confederation EBGP peers without a LOCAL_PREF
attribute. The software sends AS_CONFED_SET and accepts AS_CONFED_SET and
AS_CONF_SEQ.
