Hi Jordi: Haven't look at the draft in detail yet, but I did find it rather odd that you are using option code 46. As these are DHCPv6 option codes, this maps to:
Value Description Client ORO Singleton Option Reference 46 OPTION_CLT_TIME No Yes [RFC5007] I understand that you may have picked this simply because it is a nice number for v4/v6 transition mechanisms. But it seems like a rather odd mapping. If you really think this is a wise thing to do, you should at least document that you are requesting this because of its value (and because it would never "really" be used for RFC 8026) - not that this OPTION_CLT_TIME option itself has any meaning. It may be better to request that IANA assign a DHCPv6 option for this purpose - which should otherwise never be requested by a client (or configured on a server). - Bernie -----Original Message----- From: dhcwg <[email protected]> On Behalf Of JORDI PALET MARTINEZ Sent: Wednesday, June 13, 2018 12:46 PM To: [email protected]; [email protected]; [email protected] Subject: [dhcwg] updating RFC8026 with draft-ietf-v6ops-transition-ipv4aas Hi all, I'm sending this to Sotfwires and DHC WGs, in order to let know and seek review, but please keep the discussion only in v6ops which is responsible of this document https://datatracker.ietf.org/doc/draft-ietf-v6ops-transition-ipv4aas/ Here is the short summary of the reasons for the update. In order to prioritize the different IPv4-as-a-Service (in IPv6-only networks) transition mechanisms (so the ISP can "agree" with each CPE which one to use or even if none), we are using RFC8026 (in short "a DHCPv6-Based Prioritization Mechanism for IPv4-in-IPv6 CPEs"), which was developed in softwires, but it is a DHCPv6 based mechanism. The interesting issue is that because 464XLAT don't have an option code in RFC8026, it can't be ranked the same way, and ideally it should be, as we use also that in order to facilitate the operator to "manage" each transition mechanism status to be on/off (even to different customers). So, what we do with this update, is adding that option code for 464XLAT to the existing ones and instruct IANA about that. If you want to understand the suggested updated and how our algorithm works, you can read directly section 3.3, 7 and 10. Of course, inputs on the complete document are welcome! Thanks!
