This discussion is a sub-thread of Gyan's more generic thread.

Yes, please.

I think the draft needs to include:

 - the delegated prefix lifetime must be long lived and independent of the CE-PE link state
   it should also say something about the consequences of renumbering and how that's handled
 - the PIO is used for prefix discovery on the directly connected link, a different option
   "delegated prefix option" should be created. A principle of good protocol design is to be explicit
 - ND has been designed to be datalink type agnostic. This mechanism should not assume a 3GPP link.
   Needs text to state that this new option requires per client messaging or an underlaying p2p link.
 - Unsure if you need some way for the client to refresh or request a delegation.
 - You need to clarify host/router behaviour in that you now make the RS/RA behaviour between routers.
 - You should require a mechanism for the CE to verify forwarding state in the PE. We missed that in 3315.

Best regards,
Ole
