Abstract
An improved apparatus and method for routing of messages in a networked system wherein reduced unnecessary retransmission of messages across routers is achieved by examining the address of the source of messages to be forwarded and, if the source of the message is on the transmit side of the router, not retransmitting the message. Further, when messages are originated which do not include source subnet address information, a router receiving such a message will update the source subnet address field of the message with its own source subnet address so as to allow other routers to use the updated source subnet address information in making routing decisions.
