1  Introduction

   VPLS and PBB-VPLS are widely-deployed L2VPN technologies. Many SPs
   who are looking at adopting EVPN and PBB-EVPN want to preserve their
   investment in the (PBB-)VPLS networks. Hence, it is required to
   provide mechanisms by which (PBB-)EVPN technology can be introduced
   into existing L2VPN networks without requiring a fork-lift upgrade.
   [EVPN-VPLS] discusses mechanisms for the seamless integration of the
   two technologies in the same MPLS/IP network, however, operation is
   limited to single-active redundancy mode. In this document, we extend
   the solution to support all-active redundancy.

   Section 2 provides the limitations in the current (PBB-)EVPN/(PBB-
