Configuring a BGP confederation

BGP confederation provides another way to reduce IBGP connections in an AS.
A confederation contains sub-ASs. In each sub-AS, IBGP peers are fully meshed. Sub-ASs establish EBGP
connections in between.
Configuring a BGP confederation
After you split an AS into multiple sub-ASs, configure a router in a sub-AS as follows:
1. Enable BGP and specify the AS number of the router. For more information, see
2. Specify the confederation ID. From an outsider's perspective, the sub-ASs of the confederation is
a single AS, which is identified by the confederation ID.
3. If the router needs to establish EBGP connections to other sub-ASs, you must specify the peering
sub-ASs in the confederation.
A confederation can contain a maximum of 32 sub-ASs. The AS number of a sub-AS is effective only in
the confederation.
To configure a BGP confederation:
Command
peer { group-name | ip-address }
ignore-originatorid
Command
system-view
•

bgp as-number
