An engineer migrates from a more traditional OSPFv2 configuration that uses network commands in OSPF configuration mode to instead use OSPFv2 interface configuration. Which of the following commands configures the area number assigned to an interface in this new configuration?

An engineer migrates from a more traditional OSPFv2 configuration that uses network commands in OSPF configuration mode to instead use OSPFv2 interface configuration. Which of the following commands configures the area number assigned to an interface in this new configuration?

• The area command in interface configuration mode
• The ip ospf command in interface configuration mode
• The router ospf command in interface configuration mode
• The network command in interface configuration mode

Explanation: With OSPFv2 interface configuration mode, the configuration looks just like the traditional configuration, with a couple of exceptions. The network router subcommand is no longer required. Instead, each interface on which OSPF should be enabled is configured with an ip ospf process-id area area-id interface subcommand. This command refers to the OSPF routing process that should be enabled on the interface and specifies the OSPFv2 area.
