    allowing all traffic on the ANY links including the particular category of traffic;

    selecting a route for communication between a source node and a destination node by;

    calculating a combined route metric for each of a plurality of routes between the source node and the destination node, wherein the combined route metric calculation includes a scaling factor for increasing a route metric of each of the restricted links; and

    selecting the route with the lowest combined route metric.
