Bridges
A Bridge is a device that connects two local-area networks (LANs), or two segments of the same LAN. Unlike a router, bridges are protocol independent. They simply forward packets without analyzing and re-routing messages. Bridging occurs at layer 2 of the OSI model which is the data link layer. This means a bridge cannot read IP addresses, but only the outermost hardware address of a packet.
