what is bridging
If one or more segments of the bridged network are wireless, it is known as wireless bridging. Bridging is distinct from routing, which allows multiple different networks to communicate independently while remaining separate. A network bridge is a network device that connects multiple network segments.In the OSI model, bridging is performed in the first two layers, below the network layer. There are four types of network bridging technologies: simple bridging, multiport bridging, learning or transparent bridging, and source route bridging. is connected to bridge port 1, B is connected bridge port 2, C is connected to bridge port 3. A sends a frame addressed to B to the bridge. The bridge examines the source address of the frame and creates an address and port number entry for A in its forwarding table.
