Frog,
You have to clock the DCE end of your serial cable; 'show controller serial
x/x' will tell you which end of the cable is the DCE/DTE. If the DCE end is
connected to RTRA/RTRB, then you have to clock that interface.
However, for a closer simulation of most commercial labs around, it is more
convienent to connect the DCE end of the cable to your Frame Relay switch
and then configure clocking on the Frame relay switch.
You should not have any problem running OSPF between RTRA & RTRB.
