The IESG has approved the following document: - 'VPLS Interoperability with Provider Backbone Bridges' (draft-ietf-l2vpn-pbb-vpls-interop-05.txt) as Informational RFC This document is the product of the Layer 2 Virtual Private Networks Working Group. The IESG contact persons are Stewart Bryant and Adrian Farrel. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-l2vpn-pbb-vpls-interop/ Technical Summary This document describes different interoperability scenarios where Provider Backbone Bridge functionality is used in H-VPLS to attain better scalability. It also describes the scenarios and the mechanisms for incorporating Provider Backbone Bridge functionality within H-VPLS with existing Ethernet access and interoperability among them. Also it discusses the migration mechanisms and scenarios by which Provider Backbone Bridge functionality can be incorporated into H-VPLS with existing MPLS access. Working Group Summary This document is an L2VPN Working Group document, and has been well reviewed in the working group through multiple iterations of the draft (and it's predecessor draft). It has been essentially stable since WG adoption in January 2010. Document Quality The document is well structured and provides an exhaustive set of interoperability scenarios. Each scenario has an ASCII-art diagram and a full explanation of how the scenario operates.
