1. A method comprising:
coupling, by at least one processor, an endpoint to a first hop router in a network environment;
based on the endpoint being coupled to the first hop router in the network environment, discovering, by the first hop router and from the endpoint, multicast flow characteristics information associated with the endpoint, the multicast flow characteristics including at least one of or a combination of a per-flow capability of the endpoint and a type-length value (TLV);
propagating, by the first hop router, the multicast flow characteristics information of the endpoint to additional network nodes in the network environment, wherein a set of the additional network nodes adds one or more multicast configurations in response to receiving the propagated multicast flow characteristics information of the endpoint; and
forming, by the first hop router and at least a portion of the set of the additional network nodes, one or more multicast flows associated with the endpoint through the network environment, wherein the one or more multicast flows are formed based on the multicast flow characteristic information associated with the endpoint.
