Abstract: Techniques are described for enhancements to Protocol Independent Multicast (PIM) to enable a last hop router (LHR) to perform source discovery and directly build or join a source tree. According to the techniques of this disclosure, an LHR may be configured to receive a request to obtain multicast traffic corresponding to one or more multicast groups. The LHR may be configured to generate a source discovery join message including a request to join one or more multicast groups identified in the source discovery message and one or more source discovery flags. At least one of the one or more source discovery flags may indicate that the last hop router is interested in obtaining source information relating to at least one of the one or more multicast groups. The LHR may be configured to send, to a rendezvous point (RP) router in the network, the source discovery join message.
