It has been validated that the OSPF summary-addresses create a static route
to null0 in the newer IOS. Older versions displayed the summary route in
the table as an "O" route. Is this still the case, or do we find an "S"
there now?
We must also be careful of the objective of the question - the original
challenge was "how can /28 OSPF be redistributed into /24 IGRP on an ASBR
that cannot become an ABR". Route maps do not meet this requirement.
