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.
