confederation
Congures an identier 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 congured
Command Mode ROUTER-BGP
Usage Information
Congure 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 identied routers. You cannot have a mix of 2-byte and 4-byte identied
routers. The autonomous system number you congure 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 conguration.
NOTE: To congure these settings for a non default VRF instance, you must rst 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 (Identier)
OS10(conf-router-bgp-2)# confederation identifier 1
Example (Peers)
OS10(conf-router-bgp-2)# confederation peers 2
Supported Releases 10.3.0E or later
client-to-client
Enables route reection between clients in a cluster.
Syntax
client-to-client {reflection}
Parameters reflection — Enter to enable reection of routes allowed in a cluster.
Default Enabled
Command Mode ROUTER-BGP
Usage Information Congure the route reector to enable route reection between all clients. You must fully mesh all clients before
you disable route reection. The no version of this command disables route reection in a cluster.
