The scalability of Hierarchical Virtual Private LAN Service (H-VPLS)
with Ethernet access networks (RFC 4762) can be improved by
incorporating Provider Backbone Bridge functionality in the VPLS
access.  Provider Backbone Bridging has been standardized as IEEE
802.1ah-2008.  It aims to improve the scalability of Media Access
Control (MAC) addresses and service instances in Provider Ethernet
networks.  This document describes different interoperability
scenarios where Provider Backbone Bridge functionality is used in
H-VPLS with Ethernet or MPLS access network to attain better
scalability in terms of number of customer MAC addresses and number of
service instances.  The document also describes the scenarios and the
mechanisms for incorporating Provider Backbone Bridge functionality
within H-VPLS with existing Ethernet access and interoperability among
them.  Furthermore, the document discusses the migration mechanisms
and scenarios by which Provider Backbone Bridge functionality can be
incorporated into H-VPLS with existing MPLS access.

This document is a product of the Layer 2 Virtual Private Networks Working Group of the IETF.
