In one example embodiment, a network node of a plurality of network nodes in a multicast path is configured to provide a multicast flow from a source of the multicast flow to a receiver of the multicast flow. The network node obtains, from the receiver in a reverse direction of the multicast path, configuration instructions specifying a configuration of the multicast flow. The network node implements the configuration of the multicast flow in accordance with the configuration instructions, and provides the configuration instructions toward the source in the reverse direction of the multicast path.
