I have test on 12.1(9),
If area xx range is done at abr, it will automaticlly create a null
summary route.
If it is done at internal router (include area 0), no null summary route
in routing table.

Subject: OSPF inter-area summarization
Hi,
There is a question about OSPF inter-area summarization. In Doyle's
book,
he keep mentions that inter-area summarization does not automatically
create
a null summary route. But, in my experience, it does.
Anybody knows if it is because the ver of IOS(12.1.11 is the earliest on
routers I can use) or something else?
Thanks,
Hsieh
