Usage
Information
You can isolate problems with external routes. External OSPF routes are calculated by adding the LSA
cost to the cost of reaching the ASBR router. If an external route does not have the correct cost,
this command determines if the path to the originating router is correct. ASBRs that are not in directly
connected areas display. You can determine if an ASBR is in a directly connected area by the flags. For
ASBRs in a directly connected area, E flags are set.
