Configure Bgp Confederation-Id - Extreme Networks ExtremeWare XOS Command Reference Manual

BGP Commands

configure bgp confederation-id

configure bgp confederation-id <number>
Description
Specifies a BGP routing confederation ID.
Syntax Description
confederation-id Specifies a routing confederation identifier.
Default
N/A.
Usage Guidelines
IBGP requires that networks use a fully-meshed router configuration. This requirement does not scale
well, especially when BGP is used as an interior gateway protocol. One way to reduce the size of a
fully-meshed AS is to divide the AS into multiple sub-autonomous systems and group them into a
routing confederation. Within the confederation, each sub-AS must be fully-meshed. The confederation is
advertised to other networks as a single AS.
Use a confederation ID of 0 to indicate no confederation.
Example
The following command specifies the BGP routing confederation ID as 200:
configure bgp confederation-id 200
