confederation
Configures an identifier for a BGP confederation.
Syntax
confederation {identifier as-num | peers as-number}
Parameters
● identifier as-num —Enter an AS number, from 0 to 65535 for 2 bytes, 1 to 4294967295 for 4
bytes, or 0.1 to 65535.65535 for dotted format.
● peers as-number—Enter an AS number for peers in the BGP confederation, from 1 to
4294967295.
Default Not configured
Command Mode ROUTER-BGP
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
