Abstract

   Bit Index Explicit Replication (BIER) introduces a stateless
   multicast approach for a specific IGP area.  Segment Routing
   introduces an approach for end-to-end stateless deployment for both
   inter-area and inter-as scenarios.  This document proposes a MVPN
   using Segment Routing and BIER for a high reachability multicast
   deployment.

1.  Introduction

   Bit Index Explicit Replication (BIER) [RFC8279] introduces a
   stateless multicast approach for a specific IGP area.  Segment
   Routing [I-D.ietf-spring-segment-routing] introduces an approach for
   end-to-end stateless deployment for both inter-area and inter-as
   scenario.  An end-to-end VPN deployment may benefit from the
   combination of this two technology in which the stateless nature can
   be maintained.  This document proposes an MVPN deployment with high
   reachability in such scenario using both Segment Routing and BIER.
