Virtual Private LAN Service (VPLS) Interoperability
with Provider Backbone Bridges
Abstract
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.
