Sage,
Is there a virtual link involved in your configuration? If not send your
configs relating to OSPF from R2 and R3. Also send the output from a
"sho ip rout ospf" from R1.

Were you altering the admin distances of the routes earlier? They were
showing up with an admin distance of 170 and now have a distance of 110.

I agree, I remembered those rules the first time
somebody pointed them out on groupstudy. So these
areas are different areas I can quite safely say.

Also both the ABRs - have the same area ranges
configured on them..

R1---A0---+R2---A3
          +R3---A3

R1 is a multipoint, R2/R3 physical serials. They have
a A3 network which they are summarzing into A0, but
the summarization does not works as desired:

The A3 network, as it appears after area-range on R1:

155.10.8.0/25 [110/84] via 155.10.11.3,
              [110/84] via 155.10.11.1,
155.10.8.0/24 [110/74] via 155.10.11.3,
              [110/74] via 155.10.11.1,

Any other thoughts Brian?

rgds,
Sage
