Abstract
A method and a bridge operative to notify other bridges connected to a network of a root bridge failure by detecting a failure in a connection to the root bridge and generating a root failure suspicion notification (RFSN) bridge protocol data unit (BPDU) that includes a standard Rapid Spanning Tree BPDU portion and a failed root identifier portion uniquely identifying the root bridge which is suspected of failing. The bridge propagates the RFSN BPDU to adjacent bridges in the network to notify them of the failure.
