How is an IPv6 route learned by other PEs if OSPFv3 is used as the PE-CE routing protocol?

The correct answer is D. The PE redistributes the OSPFv3 into MP-BGP in the VPNv6 address family. When OSPFv3 runs between CE and PE, the PE learns the customer’s IPv6 routes via OSPFv3 and then injects them into MP-BGP under the VPNv6 (ipv6 vpn) address-family. This advertises the IPv6 prefixes (with RDs/RTs) to remote PEs over the MPLS core.
