Can you please send the output of
show ip ospf data
show ip ospf data extern
show ip ospf data net
as well ?
I am trying to understand how the summary route is created, to the best of
my knowledge (and testing) so far to summarize you must have a type 5 LSA to
grow the summary on and in 12.1 a type 5 LSA will not be accepted from IGRP
in redistribution if the network is part of OSPF already.
Thanks
Omer.

yes, they are both running 12.1
