Abstract: A method is provided in one example and includes broadcasting a switching node identifier associated with a first link-state protocol enabled switching node to a plurality of link-state protocol enabled switching nodes. The plurality of link-state protocol enabled switching nodes are in communication with one another by a link-state protocol cloud. The method further includes broadcasting a priority associated with the first link-state protocol enabled switching node to the plurality of link-state protocol enabled switching nodes. The method further includes broadcasting connectivity information of the first link-state protocol enabled switching node to the plurality of link-state protocol enabled switching nodes using the link-state protocol cloud. The connectivity information includes connectivity of the first link-state protocol enabled switching node with at least one spanning tree protocol enabled switching node.

Abstract: In some embodiments, a global tree structure identifying rendezvous points between a layer 1 network area and a layer 2 network area may be created. When the rendezvous point receives a data packet associated with a destination for the layer 1 network area from the layer to network area, it may forward the data packet to the destination. Non-rendezvous point devices may discard copies of the data packet.
Abstract translation: 在一些实施例中，可以创建标识层1网络区域和层2网络区域之间的会合点的全局树结构。 当会合点从层到网络区域接收到与第1层网络区域的目的地相关联的数据分组时，它可以将数据分组转发到目的地。 非会合点设备可以丢弃数据分组的副本。
