(a) is link local addressing required/supported on these types of links? (b) if so, what is their prefix length?
(c) if so, how are the IIDs automatically determined/derived? (d) if ND is switched off on multi-access technology (e.g. ethernet) point-to-point links, as the draft says it can be, how are neighbor cache entries for the remote layer 3 to layer 2 address mappings created? Manual? Promiscuous mode on the receiving end? (e) How is the situation that one end switches off ND but the other end doesn't handled? (f) if ND is switched off, how is DAD and/or NUD performed on the addresses? Link state can't be assured to be a NUD indicator on multi-access links, and DAD would be useful to prevent IID collisions when there is a 50:50 chance of getting it wrong. (g) IPV6CP uses IID of zero to indicate an unset IID, to which the peer will respond with a suggested non-zero IID - " If the two interface identifiers are different but the received interface identifier is zero, a Configure-Nak is sent with a non-zero interface-identifier value suggested for use by the remote peer. Such a suggested interface identifier MUST be different from the interface identifier of the last Configure-Request sent to the peer." How is that supposed to now work when /127s create ::0 IIDs?
