you can have clear idea by considering the two router with the redundant link connection and runing ospf
ip ospf database-filer all out:
To prevent the flooding of link-state advertisements (LSAs) on an interface. Many Internet service providers employ redundant links between OSPF neighbors. When an OSPF router receives an LSA, the LSA is flooded on all OSPF interfaces except for the interface on which the LSA was received. The ip ospf database-filter all out command enables an ISP to choose between flooding overhead and flooding reliability. For example, if there are two links between OSPF neighbors, this command can be used to prevent the flooding of LSAs on one of the links.
