Abstract

Bit Index Explicit Replication (BIER) can be used as provider tunnel for Multicast Virtual Private Network (MVPN), Global Table Multicast or Ethernet Virtual Private Network (EVPN). It is possible that not all routers in the provider network support BIER and there are various methods to handle BIER-incapable transit routers. However those methods assume the MVPN/EVPN Provider Edges (PEs) are BIER- capable. This document specifies a method to allow BIER-incapable routers to act as MVPN/EVPN PEs with BIER as the transport, by having the upstream BIER Forwarding Router (BFR) that is connected directly or indirectly via a tunnel to a BIER-incapable PE remove the BIER header and send the payload to the PE.
