IGRP can be painful if you're used to more complex and forgiving protocols.
In this instance it needs feeding with a default network. IGRP will
otherwise perform only strict classful lookups.
ip default-network n.n.0.0
Caslow recommends this route be a classful subnet 172.16.0.0 for example.
THe route is then tagged in show ip route as a 'candidate default route'
using an *.
Your IGRP routers should then follow this network as though it where 0.0.0.0

Are you using the redistribute subnets under the ospf process for igrp?
