Enter configuration commands, one per line. End with CNTL/Z.
Router9(config)#interface FastEthernet0/0
Router9(config-if)#ip ospf network ?
broadcast Specify OSPF broadcast [...]

The passive-interface configuration command effectively disables OSPF on an interface by preventing it from forming OSPF adjacencies:
Router3#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router3(config)#router ospf 44
Router3(config-router)#network 0.0.0.0 255.255.255.255 area 100
Router3(config-router)#passive-interface Ethernet0
Router3(config-router)#exit
Router3(config)#end
Router3#
A useful variant of this command allows you to make all interfaces passive by default until you explicitly enable them:
Router3#configure terminal
Enter configuration [...]
