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 flags.
For ASBRs in a directly connected area, E flags 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 flag is clear (-/-/-/).
