Abstract
The bridge device is connected to a layer-2 network. The Query message distribution unit discriminates, distributes, and outputs the normal Query messages and abnormal Query messages among the received Query messages. The abnormal message processing unit counts the number of received abnormal Query messages, and the normal message processing unit counts the number of normal Query messages. The router connection state judgment unit judges that the bridge device is a bridge device that is adjacent to the router when only the number of normal Query messages is counted and outputs an instruction to change the bridge ID to the STP processing unit. The STP processing unit establishes the bridge ID as a minimum value and renders the bridge device a root bridge.
