Bridged ethernet across the broadband provider network to the ISP router.
Each customer gets a single /64 vlan to their residence. If the customer
now wants more than one subnet, the ISP must now route additional prefixes
to a customer's gateway. The customer can't just setup a router to break
up the single /64 without the ISP carrying a route entry or the customer
doing some kind of IPv6 NAT or proxy ND. If the ISP wont route additional
prefixes, then the customer is forced to do the latter.
