Abstract
An example method includes exchanging targeted hello messages to establish a targeted neighbor connection between a first routing device and a second routing device, wherein one of the routing devices comprises a central routing device, and wherein another one of the routing devices comprises an ingress routing device. The example method further includes processing a source-active register message that specifies a source address and an identifier that are collectively associated with a multicast stream, and wherein the source-active register message further indicates whether the multicast stream is active or withdrawn. After processing the source-active register message, the example method further includes processing a list-of-receivers register message that specifies an egress routing device and at least the identifier that is associated with the multicast stream, wherein the list-of-receivers register message further indicates whether or not the egress routing device requests receipt of data associated with the multicast stream.
