RTK through RTN have Frame Relay interfaces. The four interfaces to the Frame Relay network are all on the same subnet, so the OSPF network type must be either broadcast or point-to-multipoint:

Only one end of a point-to-point circuit needs to be configured as a demand circuit. In this solution, RTC is chosen :
