The scalability of H-VPLS with Ethernet access network can be
improved by incorporating Provider Backbone Bridge (PBB)
functionality in VPLS access. PBB has been standardized as IEEE
802.1ah-2008, which is an amendment to 802.1Q to improve the
scalability of MAC addresses and service instances in Provider
Ethernet networks. This document describes different
interoperability scenarios where IEEE 802.1ah 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 PBB functionality within H-VPLS
with existing IEEE 802.1ad (aka QinQ) Ethernet access and
interoperability among them. Furthermore, the document discusses the
migration mechanisms and scenarios by which PBB functionality can be
incorporated into H-VPLS with existing MPLS access.
