Technical Summary

   This specifies an alternate technique than what has already been described
   to transport Bidir-PIM multicast traffic of a multicast VPN across a provider network.

   RFC 6513 described a method to support bidirectional C-flow using
   "Partial Mesh of MP2MP P-Tunnels".  This document describes how
   partial mesh of MP2MP P-Tunnels can be simulated with Ingress
   Replication, instead of a real MP2MP tunnel.  This enables a Service
   Provider to use Ingress Replication to offer transparent BIDIR-PIM
   service to its VPN customers.

Working Group Summary

  No controversy or rough consensus decisions.
Document Quality

  The document is of good technical quality.
  There is no known implementation yet, but one vendor has 
  mentioned plans for implementing these specs.
