This read-write object, ranging from 0 to 65535, associates a preferred route with a Frame Relay connection, with 0 meaning no preferred route is associated and the route itself defined in the cwaPrefRouteConfTable; setting this to 0 automatically sets frChanDirectRoute to false. An administrator uses it to steer a specific Frame Relay circuit over a preferred network path. For example, an engineer wanting a business-critical PVC to prefer a specific low-hop-count path through the network would configure this object with that route's identifier.
