Section 11.2 of RFC 6513 ("Partitioned Sets of PEs") describes two methods of carrying Bidirectional PIM (BIDIR-PIM) [RFC5015] C-flow traffic over a provider core without using the core as the Rendezvous Point Link (RPL) or requiring Designated Forwarder election.

       Simulating Partial Mesh of Multipoint-to-Multipoint (MP2MP)                Provider Tunnels with Ingress Replication


   RFC 6513 ("Multicast in MPLS/BGP IP VPNs") describes a method to    support bidirectional customer multicast flows using a partial mesh    of Multipoint-to-Multipoint (MP2MP) tunnels.  This document specifies    how a partial mesh of MP2MP tunnels can be simulated using Ingress    Replication.  This solution enables a service provider to use Ingress    Replication to offer transparent bidirectional multicast service to    its VPN customers.
