Abstract
One embodiment of the present invention provides a switch. The switch includes a packet processor and a spanning tree management module. The packet processor obtains information associated with a spanning tree from a message. The spanning tree management module, in response to the obtained information being superior to locally available information of the spanning tree, determines the port role of a local port of the switch for the spanning tree to be the root port and the port state of the local port for the spanning tree to be blocking.
