A method for dynamic path failover in a network with two or more redundant and interconnected bridges, is described. A first bridge operates as a root bridge and each node includes two ports where each port is coupled to a respective one of the bridges. The method includes defining a bridge identifier at a node which presents the node as a capable bridge to the two or more fully compliant, RSTP enabled MAC bridges, forwarding a BPDU message from the node that defines the node as an inferior alternate path to the root bridge, facilitating the dynamic sensing of the absence of communication between the root bridge and the node, receiving a topology change message at the node from the second redundant bridge, and sending an agreement message from the node to the second redundant bridge such that the node automatically begins receiving messages from the second redundant bridge.
