Abstract: A method, system and an apparatus to transport bidir PIM over a multiprotocol label switched network are provided. The method may comprise receiving a multicast packet at a network element, the multicast packet including an upstream label. The method may further comprise identifying, from the upstream label, a Multicast Distribution Tree (MDT) rooted at a rendezvous point. The packet may be forwarded along the MDT towards the RP based on the upstream label. The MDT may be identified from a downstream label and the packet may be forwarded along the MDT away from the RP based on the downstream label.
