Computer Networking How should a router that is being used in a Frame Relay network be configured to keep split horizon issues from preventing routing updates? Configure a separate subinterface for each PVC with a unique DLCI and subnet assigned to the subinterface. Configure a single subinterface to establish multiple PVC connections to multiple remote router interfaces. Configure many subinterfaces in the same subnet. Configure each Frame Relay circuit as a point-to-point line to support multicast and broadcast traffic.
