Techopedia Explains Bridge Router

A bridge router has the ability to work as two different devices and manage data accordingly. For example, a bridge router can provide bridging capabilities for some protocols such as Token Ring and routing capabilities for protocols such as TCP/IP. When a bridge router receives a packet, it determines whether or not it recognizes network layer protocol stack functionality. If recognized, the bridge router routes the frame using the defined routing logic. If not recognized, it forwards the data packet to the next connected segment.
