Stevie,
I am running IOS 12.0(19).
I posted my request because summary-address didn't work earlier on. But I
did it again and it did work.
Area range on the ASBR (where I want to redistribute) does not create
summary addresses that can be redistributed into IGRP but only sends them
to other ospf routers.
