ABSTRACT:
A new search protocol uses a message which a router periodically transmits onto the local LANs connected to its ports, and in response to the new protocol, all end stations receiving the message transmit their addresses to the router. The addresses transmitted to the router comprise the addresses and any other information needed by the router to reach the end station. For example, for an Ethernet LAN the layer2or MAC layer address of the end station is transmitted to the router. In the event that the protocol of the LAN uses source routing, the information transmitted to the router includes both the MAC address and the Route Information Field of the end station. In any event, the router uses the information received from the end stations to build its routing table. Then, upon receipt of the next CANUREACH message from a peer router, the desired destination end station will appear in the router's routing table, and there will be no need to waste bandwidth by transmitting search messages looking for the end station. The new protocol messages are transmitted periodically in order to keep the routing tables current is as the network changes dynamically.
