Usage Information
Configure your system to accept 4-byte formats before entering a 4-byte AS number. All routers in the
Confederation must be 4-byte or 2-byte identified routers. You cannot have a mix of 2-byte and 4-byte identified
routers. The autonomous system number that you configure in this command is 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. OS10 sends AS_CONFED_SET and accepts
AS_CONFED_SET and AS_CONF_SEQ. The no version of this command deletes the confederation
configuration.
NOTE: To configure these settings for a nondefault VRF instance, you must first enter the
ROUTER-CONFIG-VRF sub mode using the following commands:
1. Enter the ROUTER BGP mode using the router bgp as-number command.
2. From the ROUTER BGP mode, enter the ROUTER BGP VRF mode using the vrf vrf-name
command.
Example
(Identifier)
OS10(conf-router-bgp-2)# confederation identifier 1
Example (Peers)
OS10(conf-router-bgp-2)# confederation peers 2

client-to-client
Enables route reflection between clients in a cluster.
Syntax
client-to-client {reflection}
Parameters reflection — Enter to enable reflection of routes allowed in a cluster.
Default Enabled
Command Mode ROUTER-BGP
Usage Information Configure the route reflector to enable route reflection between all clients. You must fully mesh all clients before
you disable route reflection. The no version of this command disables route reflection in a cluster.
NOTE: To configure these settings for a nondefault VRF instance, you must first enter the
ROUTER-CONFIG-VRF sub mode using the following commands:
1. Enter the ROUTER BGP mode using the router bgp as-number command.
2. From the ROUTER BGP mode, enter the ROUTER BGP VRF mode using the vrf vrf-name
command.
Example
OS10(conf-router-bgp-2)# client-to-client reflection
Supported

• ip-address—Enter an IP address as the route-reflector cluster ID.
