Claim One:
1. A method of routing communications from a source network through a computer network to a destination network, comprising: for destinations and for first edge routers which interface with respective neighboring edge routers in the source network, routing selections that result in a ranking of egresses from the first edge routers to respective ones of the neighboring edge routers in the destination network, the first edge routers to interface with the source and destination networks, the routing of the selections performed by a server, which is distinct from routers of the computer network and is not one of the first edge routers or the neighboring edge routers; creating routing instructions based on a consistency requirement; and selecting an egress link from a set of egress links based on a highest rank when the consistency requirement prevents at least one of forwarding anomalies, black holing, deflection, and loop formation anomalies, the selected egress link to route the communications to the destination network.
