Steven,
The routes from r3 and r6 (172.168.30.0/24 and 172.168.60.0/24) are in the
route table on r5 as IGRP routes from r4 not OSPF routes from r3 and r6. I
had this problem and I think I fixed it by setting the distance in igrp to
higher than ospf, but I believe the correct solution is to stop routes
learnt on r4's s0 from being re-advertised to r5.
regards,
Les
