Abstract
A method is provided in one example embodiment and includes determining a source of a packet received at a network element and characterizing a link on which the packet was received. The method further includes forwarding the packet to an overlay network and locally connected hosts other than a source of the packet if the source of the packet is a local host and the link is a local link; forwarding the packet to hosts that are not dually-connected to the network element if the source of the packet is the local host and the link is a core link; and forwarding the packet as indicated in a multicast tree if the source of the packet is a non-local host and the link is a core link.
