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.

Abstract translation: 在一个示例实施例中提供了一种方法，并且包括确定在网络元件处接收的分组的源并表征其上接收分组的链路。 所述方法还包括：如果所述分组的源是本地主机，并且所述链路是本地链路，则将所述分组转发到覆盖网络和除所述分组的源之外的本地连接的主机; 如果分组的源是本地主机并且链路是核心链路，则将分组转发到不与网络元件双重连接的主机; 并且如果分组的源是非本地主机并且该链路是核心链路，则转发分组（如多播树中所示）。
