ABSTRACT:
A method for supporting dynamic configuration changes comprises receiving a message from a current root bridge, comparing a bridge media access control (MAC) address of a receiving port to a bridge MAC address of the received message, if the bridge MAC addresses are not the same, then comparing a current priority value with a previous priority value of the current root bridge, determining if the receiving port is a qualified root port, and if the port is a qualified root port, then returning a superior designated message to execute an RSTP calculation.
