As I know, OSPF stub area is used to reject type 3,4,5 LSA
Type 5 LSA is considered as External route
Type3 LSA is considered is Inter-area route
How about Type 4 LSA ?
According to below connection, can I form virtual link between Router Area3 to Area0 ?
Router Area3 <-> Router Stub area 2 <-> Router Area0 <-> Router Rip
