Maybe I'm missing something. I would expect the edge router to maintain a
mapping from prefix to vlan. It can then use normal neighbor discovery to
find the mac address for a CPE.

The access node is mostly a bridge. But it may have to filter on mac address
(and prohibit direct CPE-to-CPE communication) to increase security a bit.
