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.
