Hi, On Thu, Nov 28, 2019 at 03:04:45PM +0100, Ole Troan wrote: > Or in general, if you send a set of DH options to a host, why do you think it should blindly process those packets? iirc the DestOptions packets sent as part of the experiments being the basis for RFC 7872 were sent with PadN options. As for those RFC 8200 states: "These padding options must be recognized by all IPv6 implementations" There's a somewhat ironic element here. Pretty much all IPv6 implementations I know (and the people actually coding them, at least as far as I know that group) take RFC 8200 (or 2460, in those days) as a basis for specific implementation decisions. RFC 8200 - from my reading - somewhat invokes an 'universal notion of IPv6 extension headers'. So far the theory. Now actual experiments (from, as a look at the list of authors of RFC 7872 implies, people with a lot of knowledge re: IPv6 and, more importantly, operating experience from some very large networks) show that said 'universal notion' seems flawed (for whatever reasons). So far the practice. And to question the results of those experiments the question is asked: "why was there an expectation that real-life systems process those packets"? cheers Enno -- Enno Rey Cell: +49 173 6745902 Twitter: @Enno_Insinuator
