How can you change the OSPFv3 interface cost in the configuration?

ipv6 ospf cost COST NUMBER
set ospf cost COST NUMBER
ospf interface cost COST
cost ipv6 ospf COST NUMBER

The correct answer is: ipv6 ospf cost COST NUMBER

The correct approach to change the OSPFv3 interface cost is through the command that specifies the interface's OSPF cost directly within the context of the interface configuration mode. The command "ipv6 ospf cost COST NUMBER" effectively allows you to set the cost associated with that particular OSPFv3-enabled interface. In OSPF (Open Shortest Path First) routing, the cost metric is crucial as it influences the OSPF path selection process; lower costs are preferred. By configuring the cost directly on the interface, you can dynamically adjust the way routing decisions are made for traffic flowing through that interface. Other choices do not align with the correct syntax or structure used in Cisco devices for configuring OSPFv3. Consequently, they wouldn't work as valid commands within Cisco's operating system.
