11.2.3 Configuring OSPF Apply

Points to note

• Exchange of LSAs with neighboring routers is enabled on an interface when the network address for the interface matches the range of addresses specified by the network command.

• If you are not using multiple areas, make sure that the same area ID is set on all OSPF routers.
