Hmm, unless the DSL deployment is explained better in an IETF document
we will thrash forever discussing issues in DSL.  So now I can only
reply based on a guess for what the DSL network may look like.  Why is
the BNG not using some identifier like a line id and not letting another
customer spoof a LL address in the BNG's neighbor cache?  The  DSL
broadband standards should be able to fix such a basic problem.
