As I suspected - check your router D routing table. this one is a classic problem, and one you MUST be able to solve in advanced studies.
the question remains - why is it that IGRP is not seeing the subnets out of the OSPF domain? How do you correct the problem? My previous posts contained some of the answer. Think "classfull" in terms of IGRP behaviour.

These are the routing table outputs and trace routes outputs from the routers: Any ideas?? Thanks.
