How do VPNv6 routes propagate between CEs?

The correct answer is C. The PE assigns an RD to each VRF and prepends the value to shared IPV6 routes, which allows. In an IPv6 VPN, each PE prepends a unique Route Distinguisher to IPv6 prefixes in its VRF before advertising them via BGP. This RD+IPv6 NLRI mechanism keeps identical IPv6 subnets at different sites distinct in the MPLS backbone.
