What is the result of a router being configured with OSPFv3 for IPv6 when no explicit RID is configured and there are no active IPv4 interfaces?

What is the result of a router being configured with OSPFv3 for IPv6 when no explicit RID is configured and there are no active IPv4 interfaces?

• The RID is set to 0.0.0.0 and does not allow adjacencies to form.
• The RID is set to the first 32 high order bits of the lowest IPv6 address configured on the router.
• OSPFv3 running IPv6 does not require a RID and IPv6 router adjacencies will form normally.
• A RID will be automatically generated once an adjacency with another OSPFv3 router is formed.

Explanation: OSPFv3 routers require a valid RID before adjacencies with other OSPFv3 routers can form. A RID can be configured manually using the router-id command or dynamically based on an active IPv4 address.
