OSPF route redistribution gotcha

An often fogotten rule in OSPF is that in order to redistribute a route, the next hop must be an INTERNAL route in ospf. If you point to an interface that does not have a network statement or you did redistribute connected because you know that interface would not have any OSPF neighbors, the prefix would sho up in the sho ip ospf data BUT would not have the routing bit set so would not be redistributed.
