Ole - should we ask Markus to kick http://tools.ietf.org/html/draft-stenberg-pd-route-maintenance-00 back into life? Alex - With respect to the need of combining that other solution, not being independent, I think Leaf could explain that. Right? I read draft-petrescu here targets the routing issue on the relay, which sounds a network component not included in the Fig.1 titled 'Possible prefix delegation deployment cases' in the draft-stenberg. I guess the draft-stenberg might intend to suggest some so-called 'approaches' for the Requesting Routers (RR) or Delegating Routers (DR), or even Backend provisioning system against some (frankly speaking, vague) issues, but not for the relay agent of DHCPv6. I also have not read out the solid protocol enhancement for DHCPv6 from draft-stenberg yet.

Yes, I think such text with that analogy could help clarify. I will be happy to include you as co-author if you provided text. Yes, why not ask Markus to kick that other draft back into life? With respect to the need of combining that other solution, not being independent, I think Leaf could explain that. Right?
