Abstract
The present invention includes a method, a system, and a computer readable medium for establishing a connection between hosts in a computer network with the connection configured for symmetrical forward and reverse routing. The method uses the following steps. First, a first host local routing table to route a packet from a first host to a first gateway according to a routing protocol. Next, the first gateway local routing table routes the packet from the first gateway to a first access router. After that, a first access router local routing table routes the packet from the first access router to a second access router. Then, a second access router local routing table routes the packet from the second access router to a second gateway. Finally, a second gateway local routing table routes the packet from the second gateway router to a second host.
