Definition - What does Bridge Router mean?
A bridge router is a type of network device operating as both a bridge and a router.
It forwards the frames to the connected segments or a LAN when there is no routing information. It also routes all other TCP/IP packets to different networks. The bridge router operates at the network and data link layer of the OSI Model.
This term is also known as a brouter.
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.
