4 important questions on OSPFv3 Configuration

Instead of using network statements it has to be done using an interface configuration command:
IPv6 OSPF <process id> Area <area id>

What are the 4 steps to configure OSPFv3?

1. Initialize the routing process, first ipv6 unicast-routing should be enabled, afterwards router ospfv3 <process id> can be used to activate the process.
2. Define router id. If none configured and no ipv4 addresses are available it is configured as and no adjacensies can be formed.
3. Optional: enable address family by using address-family <ipv6|ipv4> unicast.
4. Enable OSPFv3 on an interface by using ospfv3 <process-id> ipv6 area <area-id>
