I'm sending a /64 today. I've not tried a /56 or /48 PD, but
presumably AirOS will either take a /64 from the larger prefix and
put it on the LAN or put the whole /56 or /48 prefix on the LAN.
Either way, AirOS isn't going to do DHCP-PD on the LAN, but you
could do it manually. Clearly, this functionality resides squarely
in the customer's router. If I sent a /48 to it, I'll have a v6
route to the /48 via the PPPoE iface and fictitious link-local fe80
address. The /48 can be subnetted as needed internal to the LAN, I
won't care as the provider.
FWIW, I'm well aware of the recommendation of giving /56 or even /48
to all subscribers. I also know of no consumer router that can use
anything other than a /64 for it's LAN side so I've left it alone.
Switching from /64s to /56s or /48s to subscribers is an easy
conversion and when the day comes that someone asks for a static v6
prefix, I'll give them a /48 or more if they want it.

So now how does this work with multiple
subnets, prefixes, etc.? If I had an internal router that
further sub-delegated prefixes, would I change that /64 to a
/56? What size of prefix is sent down to the CPE from your
router?

We do this every day using AirRouters and XM/XW CPEs. They're
in router mode, PPPoE, getting v6 via PD and auto-configuring
the LAN side.

Has anyone successfully gotten ipv6 PD to work on ubnt devices running pppoe and configured in router mode?
Also does ubnt not plan on putting any v6 features in the v8.0?
