Abstract: In one illustrative example, a network node connected in a network fabric may identify that it is established as part of a multicast distribution tree for forwarding multicast traffic from a source node to one or more host receiver devices of a multicast group. In response, the network node may propagate in the network fabric a message for advertising the network node as a candidate local source node at which to join the multicast group. The message for advertising may include data such as a reachability metric. The propagation of the message may be part of a flooding of such messages in the network fabric. The network node serving as the candidate local source node may thereafter “locally” join a host receiver device in the multicast group at the network node so that the device may receive the multicast traffic from the source node via the network node.

Abstract: Systems and methods provide for the dynamic discovery, update and propagation of multicast streams capabilities in a network. An endpoint can be coupled to a first hop router in a network environment. The first hop router can discover multicast flow characteristics information associated with the endpoint and propagate the multicast flow characteristics information of the endpoint to additional network nodes in the network environment. The first hop router and at least a portion of the additional network nodes can form one or more multicast flows associated with the endpoint through the network environment using the multicast flow characteristic information associated with the endpoint.

Abstract: In one embodiment, a node in a communication network receives a request for messages of a particular group, determines a rendezvous point, and transmits the request to the rendezvous point to cause the rendezvous point to return a source-message indicating a source-node of the particular group. The node further creates a path from itself to the source-node and receives messages of the particular group according to the path.
