I'll go out on a limb here and say that RA is not needed for DHCPv6. A DHCPv6 client multicasts all its messages to the well-known all-relays-and-servers address. A client needs only its link-local address to do this. The relay (or server if it happens to be on the same link) can thus talk to the client in the complete absence of RA.
