What OSPF command, when configured, will include all interfaces into area 0?
network 0.0.0.0 255.255.255.255 area 0
network [IP address] [wildcard-mask] area [area-id]
For OSPF to operate on the interface, the primary address of the interface must be covered by the network area command. If the network area command covers only the secondary address, it will not enable OSPF over that interface.
