A high-level overview of network bridging, using the ISO/OSI layers and terminology

Network bridging is the action taken by network equipment to create an aggregate network from either two or more communication networks, or two or more network segments.[1] 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.[2]

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.[3]

There are four types of network bridging technologies: simple bridging, multiport bridging, learning or transparent bridging, and source route bridging.[4][5]
