bgp confederation-id

This command configures the BGP router to be a member of a BGP confederation.

Syntax

bgp confederation identifier confed-id
no bgp confederation identifier confed-id

Parameters

confed-id Specifies a confederation identifier value. Valid values are 1 - 65535.

Defaults

None.

Mode

BGP Router Configuration.

Usage

A BGP router can be configured to be a member of a BGP confederation when an AS is large and you wish to break it up into smaller groupings or where the network is subdivided into several AS‘s and you want to group members of multiple ASs. When configured as a confederation member, the router represents itself as the configured AS number to confederation peers and as the configured confederation identifier to non-confederation peers.

The no bgp confederation identifier command removes the configured confederation peer identifier for this router.

Example

The following example configures the BGP router to be a member of BGP confederation 100:

System(su-config)->router bgp 65151
System(su-config-bgp)->bgp router-id 151.1.1.9
System(su-config-bgp)->bgp confederation-id 100
System(su-config-bgp)->
