Hi Group,
I think you can summarize your area 0 routes to other
non-backbone areas as long as you use area 0 range
command on all your ABR's. I will have to try
though..technically area 0 is like any other normal
area except that it is transit for all inter-area
traffic and you should be able to summarize area 0
into one route.
