Usage Information To isolate problems with external routes, use this command. In OSPF, external 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, use this
command to determine if the path to the originating router is correct. The display output is not sorted in any order.
NOTE: ASBRs that are not in directly connected areas are also displayed.
You can determine if an ASBR is in a directly connected area (or not) by the ags. For ASBRs in a directly
connected area, E ags are set. In the following example, router 1.1.1.1 is in a directly connected area since the Flag
is E/-/-/. For remote ASBRs, the E ag is clear (-/-/-/).
