Which command would you use to enable OSPF on a router interface?

The command to enable OSPF on a router interface allows you to specify which interfaces will participate in OSPF routing by defining the networks on which OSPF should be activated. The correct option accomplishes this through the use of the network command, which is fundamental in OSPF configuration.

When you use the command to specify a network address and a wildcard mask along with an area ID, you are instructing the OSPF process to include all interfaces that match the specified network criteria into the defined OSPF area. This is how OSPF identifies and includes interfaces in its routing process.

By defining these parameters, the router interfaces that match the criteria are enabled for OSPF, thus allowing the OSPF process to establish adjacencies and exchange routing information on those interfaces. This is essential for the dynamic discovery of network paths and for OSPF to function properly within a given area of the network.

In contrast, other commands listed do not configure OSPF in the same way. The command for enabling OSPF in an interface context does not directly match the function of the router ospf command, which brings up the OSPF routing process itself, nor does it set the parameters for interface
