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 (-/-/-/).
