Multiple Shortest-Path Tree Protocol

In accordance with on example, a control packet from a first network device is received at a second network device. The control packet comprises, embedded in a source address field of the control packet, control information for a spanning tree associated with a root network device. The control information is extracted from the source address field of the control packet in order to populate a shortest-path forwarding table. A data packet from the first network is then received by the second network device. Based on the shortest-path forwarding table and a media access control (MAC) address table, a host device to which the data packet is directed is identified. Finally, based on the information in the shortest-path forwarding table and the MAC address table, the data packet is forwarded to a network device directed connected to the host device.
