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.
