RE: Summarizing LSA-3 in ospf

Probably because by definition your O IA (inter-area) are ALREADY type 3
LSAs and were received as a summary.

You could always use a total stub area if you just wanted to get rid of
them. :)

No dear, I am unable to get the desired results. Kindly lab it for
confirming me. I came to know that, in the command "area <*id*> range" ,
this* id* must be the area id when these specific routes reside. I just
wanna know the logic, why i am unable to send the summary of OIA routes?

Thanks,
