The IESG contact persons are Bill Fenner and Ross Callon. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-idr-rfc3065bis-07.txt
Technical Summary The Border Gateway Protocol (BGP) is an inter-autonomous system routing protocol designed for Transmission Control Protocol/Internet Protocol (TCP/IP) networks. BGP requires that all BGP speakers within a single autonomous system (AS) must be fully meshed. This represents a serious scaling problem that has been well documented in a number of proposals. This document 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. The intention of this extension is to aid in policy administration and reduce the management complexity of maintaining a large autonomous system. Working Group Summary Working Group Last Call resulted in some issues which were addressed in an update to the draft. Protocol Quality Bill Fenner reviewed this spec for the IESG. The Implementation Report is available at http://www.ietf.org/IESG/Implementations/implem_RFC3065bis.txt Note to RFC Editor This document obsoletes RFC 3065.
