The SP router has a route for the entire delegated prefix, with as nexthop the
link local address of the CPE.

So I don't see how this could possibly go wrong.

Like I said, from the point of view of the SP router, assigning an address
to a virtual interface or to the WAN interface is almost indistinguishable.
