BGP Commands

configure /jointfilesconvert/484795/bgp add confederation-peer sub-AS-number

configure /jointfilesconvert/484795/bgp add confederation-peer sub-AS-number <number>

Description

Adds a sub-AS to a confederation.

Syntax Description

Default

N/A.

Usage Guidelines

Invoke this command multiple times to add multiple sub-ASs.

IBGP requires networks to 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, all BGP speakers in each sub-AS must be fully-meshed.

The confederation is advertised to other networks as a single AS.

Example

The following command adds one sub-AS to a confederation:

configure /jointfilesconvert/484795/bgp add confederation-peer sub-AS-number 65002

number Specifies a sub-AS number.
