Abstract

See full text

A system, method, and Ethernet bridge utilizing forced MAC learning to set up a path from an originating node, PON (23) to one or more terminating nodes, PTN (12) through intermediate bridge nodes (14, 21). In the point-to-point case, a Previous Hop Bridge (PHB) list defines the links in the path. Each link includes a destination address, source address, port number, and VID. A path learning frame (13, 19, 22) containing the list is sent in reverse order from the PTN through the intermediate bridge nodes to the PON. Each node in the path saves the received frame's header information as learned path information using standard MAC learning functionality, removes the node's own information from the list, and forwards the frame with the remainder of the list to the next node using the port specified by the port number for that link. When the frame arrives at the PON, all nodes have saved the learned path information.
