ICND2: Interconnecting Cisco Networking Devices Part 2 (legacy) — Question 39

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, E

Explanation

Configuring a router ID is necessary for OSPFv3 to identify the router in the OSPF domain, while enabling IPv6 unicast routing is crucial for OSPFv3 to function correctly with IPv6 networks. The other options, such as configuring an autonomous system number and a loopback interface, are not required for OSPFv3, as it does not use autonomous system numbers in the same way as OSPFv2.
