Maybe, but I'm not convinced.

I don't think so.

The missing step here is that they should be providing you with a global
address somehow, and really a /48. Did they convey that to you out of
band? Or is that supposed to be in some PPP options? Have you
configured it? Did they say they want to run RIPng with you? See is@'s
mail - I suspect that's closer to what you want.
