            Encapsulation for BIER in Non-MPLS IPv6 Networks
                  draft-xie-6man-bier-encapsulation-02

Abstract

   Bit Index Explicit Replication (BIER) introduces a new multicast-
   specific BIER Header.  Currently BIER has two types of encapsulation
   formats: one is MPLS encapsulation, the other is Ethernet
   encapsulation.  This document proposes a BIER IPv6 encapsulation for
   Non-MPLS IPv6 Networks using an IPv6 Destination Option extension
   header.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

1.  Introduction

   Bit Index Explicit Replication (BIER) [RFC8279] is an architecture
   that provides optimal multicast forwarding without requiring
   intermediate routers to maintain any per-flow state by using a
   multicast-specific BIER header.  [RFC8296] defines two types of BIER
   encapsulation to run on physical links: one is BIER MPLS
   encapsulation to run on various physical links that support MPLS, the
   other is BIER Ethernet encapsulation to run on ethernet links, with
   an ethertype 0xAB37.  This document proposes a BIER IPv6
   encapsulation for Non-MPLS IPv6 Networks using an IPv6 Destination
   Option extension header.
