Kevin,
A distribute list can be used to control the routes in OSPF but you have to apply them on the receiving router rather than on the sending router which you would traditionally do. This is because the routes are sent via LSAs.
If you apply the distribute list and perform a "show ip route ospf" the route should NOT be in the routing table....
However if you do a "show ip ospf database" the network will still be there. This means that when the second router sends out LSA's to say router 3 the route will get propagated. To get over this you would need to apply an inbound distribute lists to every router you don't want to know the routes you want to filter.
Best regards
David
