Abstract
A method of allowing TCP/IP resources to be rerouted to another active link connected to the same resources in a timely manner. This method comprises sending a Routing Information Protocol (RIP) update to the router by sending information to the other resource specifying a metric that indicates that the desired network is unreachable; this RIP update is sent with the IP source address set as if it had been transmitted across the failed link. This causes the route to be updated to indicate that the failing link is no longer active and indicate an alternate route as the preferred means of reaching the resource.
