I think this is it. My setup has one address on my upstream interface (a tunnel), within a /64 that is shared between me and the tunnel endpoint, and another /64 for my local LAN with an address from that on my router. I am unclear on if you need a rtadvd.conf. But you definitely need a globally routed /64 prefix and address configured on the LAN-facing interface. You can also use tcpdump to look for icmp6 and see the RAs.
