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.
