Conditional OSPF default route origination based on classless IP prefixes
Symptom: The early implementations of the Conditional OSPF default route origination feature expected a route-map which referred to an IP access-list. The IP access-list was allowed to match only classful prefixes (class-A, class-B or class-C networks).
