Usage Information
When a BGP cluster contains only one route reector, the cluster ID is the route reector’s router ID. For
redundancy, a BGP cluster may contain two or more route reectors and you assign a cluster ID with the bgp
cluster-id command. Without a cluster ID, the route reector cannot recognize route updates from the other
route reectors 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
displays as an integer.
Related Commands
bgp client-to-client reection — enables route reection between the route reector and the clients.
neighbor route-reector-client — congures a route reector and clients.
show ip bgp ipv6 unicast cluster-list — views paths with a cluster ID.
bgp confederation identier
Congure an identier for a BGP confederation.
Syntax
bgp confederation identifier as-number
To delete a BGP confederation identier, use the no bgp confederation identifier as-number

Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
The autonomous systems congured 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.
The system 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 confederation peers
Specify the autonomous systems (ASs) that belong to the BGP confederation.
Syntax
bgp confederation peers as-number [...as-number]
To remove bgp confederation peers, use the no bgp confederation peer command.
