Abstract: A system and method for integrating redundant ring and rapid spanning tree protocol (RSTP) are disclosed. By setting a mode message and a group ID for each of a plurality of ring nodes within a redundant ring, so that in a scenario that the redundant ring and the RSTP are running concurrently on a network environment, forwarding a bridge protocol data unit (BDPU) to a matching network topology is allowed when the mode message is transparent mode, and each of the respective network topology is converged to a steady state RSTP domain. The mechanism is help to improve the scalability of the network architecture.
