Difference between Routers and Bridges

Distinguish, differentiate, compare and explain what is the Difference between Routers and Bridges. Comparison and Differences.


Bridges operates in both the physical and the data link layer. As a physical layer device, it regenerates the signal it receives. As a data link layer device, the bridge can check the PHYSICAL/MAC addresses (source and destination) contained in the frame. A bridge has a table used in filtering decisions. It can check the destination address of a frame and decide if the frame should be forwarded or dropped. If the frame is to be forwarded, the decision must specify the port. A bridge has a table that maps address to ports. Limit or filter traffic keeping local traffic local yet allow connectivity to other parts (segments).


Routers are identified as Layer-3 devices, as routers process logical addressing information in the Network header of a packet (such as IP addresses).
