UBS is Layer 3 between the ISP and Telecom, but effectively the L2TP tunnel creates a layer2 link between the customer and the ISP's LNS. So theoretically I would have thought it could support v6 without a problem. The question however is why ? and to where would the v6 packets actually transit. I believe the WorldExchange guys are running v6 throughout their network, all though I don't know if it transits anywhere, and turning that into an available product is a whole different story all together.

The last I knew (which was admittedly many years ago) Telecom's wholesale DSL was a layer-3 service, with frames being routed through a twisty maze of RFC1918-numbered routers before they arrived at the user's ISP. If that was still the case, then surely Telecom would need to route v6 frames between the customer and the ISP for the customer to receive native v6 service?
If there has been a subsequent layer-2 wholesale DSL service offered, along the lines that is done elsewhere, is there not still a requirement for Telecom to switch v6 frames from PPPoA into L2TP, or whatever framing is used to present a user's traffic to an ISP?
