I know it. But Cisco behaves exactly like Quagga after applying my 
patch - ABR originates default into stub in any case. In totally stub 
case default is just only type-3 summary it inserts into area.

NSSA case is worse. Actual problem is that default must be type-3 
summary if summaries are disabled and type-7 external if summaries 
are enabled. Yes, it's this way, not oposite - see RFC 3101 1.3.

I'll put making originating default into nssa (and maybe into stub) 
configurable into my TODO, but it will not in high place in this 
list. I still (even after drinking first cup of coffee) can't think 
of case where I'd want to disable ABR originating default into nssa 
area. I'd better fix "nssa summaries enabled" case - ie. originating 
type-7 in this case.
