                 RSVP-TE Extensions for P2MP-based BIER
                 draft-xie-mpls-rsvp-bier-extension-01

Abstract

   Bit Index Explicit Replication (BIER) is a new architecture that
   provides optimal multicast forwarding without requiring intermediate
   routers to maintain any per-flow state by using a multicast-specific
   BIER header.  This document describes extensions to Resource
   Reservation Protocol - Traffic Engineering (RSVP-TE) for the set up
   of Traffic Engineered (TE) point-to-multipoint (P2MP) Label Switched
   Paths (LSPs) with BIER infomation, which is called P2MP based BIER in
   [I-D.xie-bier-mvpn-mpls-p2mp].

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].
