         VPLS Interoperability with Provider Backbone Bridges  
                 draft-ietf-l2vpn-pbb-vpls-interop-04 

Abstract

   The scalability of H-VPLS with Ethernet access networks can be
   improved by incorporating Provider Backbone Bridge functionality in
   the VPLS access. Provider Backbone Bridging has been standardized as
   IEEE 802.1ah-2008, and aims to improve the scalability of 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.
