Refer to the exhibit. Based on the output shown, how are the OSPFv3 address families configured this router?

• The IPv6 address family is configured for both Area 0 and Area 1.
• The IPv4 address family is configured for Area 1, IPv6 for Area 0.
• The IPv4 address family is configured for Area 0, IPv6 for Area 1.
• The IPv4 address family is configured for both Area 0 and Area 1.

Explanation: The instance ID 0 is for IPv6 unicast and instance ID 64 is for IPv4 unicast. OSPFv3 runs on top of IPv6 and uses IPv6 link-local scope (FE80::/10) for control packets. As a consequence, it is required that IPv6 be enabled on an OSPFv3 link although the link may not be participating in any IPv6 routing. For OSPFv3 AFs, both OSPF for IPv4 and OSPF for IPv6 use IPv6 to exchange routing information. Therefore, IPv6 unicast routing must be enabled on the routers.
