Yes that is what I have been trying to do. I have a static route pointing to
the Dialer0 interface of an ADSL connection. I am then running EIGRP from R1
to R2 and using default-information originate. R2 is then running OSPF into
area 0 and you see the EIGRP default route tunr up in the route table as E2
0.0.0.0/0, I just can't seem to get that route back into the IGRP process. I
have used default-network 10.0.0.0 on the IGRP router and also IGRP 10.0.1.0
which is the EIGRP AS, however this doesn't seem to set the gateway of last
resort or set up a default route/network so when I try to ping past the
egress router from the IGRP AS I can't get return traffic with oout a static
route to the gateway of last resort so to speak.
Cheers

if i understand this question correctly , you want a default route which
comes from OSFP domain to be redistributed and shows up in teh down
stream routes of the IGRP .
as you know IGRP doesnt understand 0.0.0.0 network , so the only way to
propagate default to it is to use the ip default-network .
to get the default propagte to down stream routers you have to make sure
of those
1-make the default network a major class network (not a subnet where you
end up with static route to null of for the major of this subnet )
2-advertise the major class network into your IGRP process ,otherwise
the default route will not propagate .
