RFC3065bis Implementation Report


Abstract


This document provides an implementation report for Autonomous System
Confederations for BGP as defined in draft-ietf-idr-
rfc3065bis-05.txt.

The editor did not verify the accuracy of the information provided by
respondents or by any alternative means. The respondents are experts
with the implementations they reported on, and their responses are
considered authoritative for the implementations for which their
responses represent.


1. Introduction


Autonomous System Confederations for BGP describes an extension to
BGP which may be used to create a confederation of autonomous systems
that is represented as a single autonomous system to BGP peers
external to the confederation, thereby removing the "full mesh"
requirement inherent to BGP. The intention of this extension is to
aid in policy administration and reduce the management complexity of
maintaining a large autonomous system.

This document provides an implementation report for Autonomous System
Confederations for BGP as defined in draft-ietf-idr-
rfc3065bis-05.txt.

The editor did not verify the accuracy of the information provided by
