Networks: Bridges4 Bridges Operate at the data link layer. Bridges use backward learning in recording source address on transmissions. Unlike repeaters, bridges will not forward a frame onto another LAN segment if it knows about the location of the destination node. Bridge management gets more complicated when loops are possible in the frame route.
