Abstract: An example method includes receiving, by a first hop router (FHR) and from a source device, multicast stream data associated with a multicast stream, sending, from the FHR and to a rendezvous point (RP) using a Protocol Independent Multicast (PIM) protocol, one or more null register messages that are each associated with the multicast stream. Each of the one or more null register messages includes a source address and a group address that are collectively associated with the multicast stream, and each of the one or more null register messages further includes an indication to request that the RP refrain from sending any register-stop messages associated with the multicast stream to the FHR. The example method further includes, after sending the one or more null register messages that are each associated with the multicast stream, sending, to the RP, the multicast stream data in a non-encapsulated format.
