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

• configure an autonomous system number
• configure a loopback interface
• configure a router ID
• Enable IPv6 on an interface
• Enable IPv6 unicast routing

Explanation: Before you enable OSPF for IPv6 on an interface, you must perform the following:+ Complete the OSPF network strategy and planning for your IPv6 network. For example, you must decide whether multiple areas are required.

+ Enable IPv6 unicast routing.
+ Enable IPv6 on the interface.Reference: https://www.cisco.com/c/en/us/support/docs/ip/ip-version-6-ipv6/112100-ospfv3-config-guide.html

Note: If we have already had an active interface, we don’t need to configure the router ID for OSPFv3 anymore because the device will automatically choose that IPv4 address for its router ID).
