CCNA Routing and Switching (legacy) — Question 17

Which two steps must you perform on each device that is configured for IPv4 routing before you implement OSPFv3? (Choose two)

Answer options

• A. configure an autonomous system number
• B. configure a loopback interface
• C. configure a router ID
• D. Enable IPv6 on an interface
• E. Enable IPv6 unicast routing

Correct answer: C

Explanation

The correct answer is C, as configuring a router ID is essential for OSPFv3 to function correctly. Options A, B, and D are not required steps for OSPFv3 implementation, and while enabling IPv6 unicast routing is important, it is not one of the two steps asked in this context.
