Let me ask some additional clarification questions. Figure 1 contains both Hosts and RGs (residential gateways).
Is it a requirement that there be a single RG at each customer site, and that RG then connects to the AN? In other words, is the Edge Router sending RAs only to the RG, and is it the RG that is sending RSes? Or, is the RG optional, and can one (or more Hosts) connect directly to the AN? (I'm trying to understand who the Edge Router needs to send unicast RAs to, and how it can keep track of who it needs to send such packets to. It would be considerably easier to do this if there was only one device per customer. But if the customer may just be bridged to the AN and Edge Router without having its own router at the edge, things would seem more complicated, and an Edge Router would need to send multiple unicast RAs to each customer site -- one for each device on customer site!!!)
