Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 4

Which configuration adds an IPv4 interface to an OSPFv3 process in OSPFv3 address family configuration?

Answer options

• A. router ospfv3 1 address-family ipv4
• B. Router(config-router)#ospfv3 1 ipv4 area 0
• C. Router(config-if)#ospfv3 1 ipv4 area 0
• D. router ospfv3 1 address-family ipv4 unicast

Correct answer: C

Explanation

The correct answer is C, as this command is used to associate an IPv4 interface with an OSPFv3 process directly in interface configuration mode. Options A and D pertain to address-family commands but do not apply directly to an interface, and option B is incorrectly formed for interface configuration.
