     Seamless Multicast Interoperability between EVPN and MVPN PEs
          draft-sajassi-bess-evpn-mvpn-seamless-interop-00.txt

Abstract

   Ethernet Virtual Private Network (EVPN) solution is becoming
   pervasive for Network Virtualization Overlay (NVO) services in data
   center (DC) networks and as the next generation VPN services in
   service provider (SP) networks.

   As service providers transform their networks in their COs toward
   next generation data center with Software Defined Networking (SDN)
   based fabric and Network Function Virtualization (NFV), they want to
   be able to maintain their offered services including multicast VPN
   (MVPN) service between their existing network and their new SPDC
   network seamlessly without the use of gateway devices. They want to
   have such seamless interoperability between their new SPDCs and their
   existing networks for a) reducing cost, b) having optimum forwarding,
   and c) reducing provisioning. This document describes a unified
   solution based on RFC 6513 for seamless interoperability of multicast
   VPN between EVPN and MVPN PEs. Furthermore, it describes how the
   proposed solution can be used as a routed multicast solution in data
   centers with EVPN-IRB PEs per [EVPN-IRB].
