I think this discussion somewhat misses the point because some folks feel informational roadmap documents have more weight than they actually do (according to IETF procedures, or even in practice in vendors' feature planning). (E.g., there was similar discussion about RFC4614.) The node requirements document, despite its misleading title, is INFORMATIONAL. It does not represent IETF consensus, so even if the document would say every IPv6 node MUST implement IPsec, it would mean basically nothing. Where is a Standards Track or BCP document that says IPsec is mandatory? If vendors need to make tradeoffs of what they implement or don't implement, that's their call. They can't call that product to be "RFC4294 compliant", "RFC4301 compliant", claim it supports IPsec, or claim it's "RFCxxxx" compliant (where xxxx corresponds to an RFC number which mandates IPsec). That's all. The product also might not get IPv6 ready logo certifications and such, but that's not IETF's business anyway. -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds."
