             Inter-Domain Multicast Deployment using BIERv6
                  draft-geng-bier-ipv6-inter-domain-00

Abstract

   Bit Index Explicit Replication IPv6 encapsulation (BIERv6) introduces
   an approach to use IPv6 extension header to carry BIER header with
   IPv6 unicast address as destination address.  It provides the ability
   to replicate a packet from one router to another router in a
   different domain as well as in the same domain.  This document
   introduces the techniques for multicast deployment across multiple
   domains using BIERv6, and demonstrate how BIERv6 is beneficial for
   such deployment.

1.  Introduction

   Bit Index Explicit Replication [RFC8296] IPv6 encapsulation (BIERv6)
   described in [I-D.xie-bier-ipv6-encapsulation] introduces an approach
   to use IPv6 extension header to carry BIER header.  One BIERv6
   option, using IPv6 unicast address as destination address provides
   the ability to replicate a packet from one router to another router
   in a different domain as well as in the same domain.  This document
   introduces the techniques for multicast deployment across multiple
   domains using BIERv6, and demonstrates how BIERv6 is beneficial for
   such deployment.

2.  Terminology

   Readers of this document are assumed to be familiar with the
   terminology and concepts of the documents listed as Normative
   References.
