Usage Information To isolate problems with inter-area and external routes, use this command. In OSPF inter-area and external routes
are calculated by adding LSA cost to the cost of reaching the router. If an inter-area or external route is not of
correct cost, the display can determine if the path to the originating router is correct or not.
