I thought(and I may well be wrong) you could only create a summary on the
router which is advertising the "networks/links" into ospf

>the ABR creates summaries when sending 1/2 into another area as O IA (LSA
3) (using area x range)

>the ASBR creates a summary ON THE ROUTER where the external network is
being advertised, as a type 5 / type 7 lsa.

Every lab I have ever done ,has always had the originating router advertise
the summary ,not another

>the "area x range" command will not have an effect on a non-abr
>I think you are talking about "summary-address"
