Folks, I think that we heard the following at yesterday's meeting:
Title ===== The document should be renamed "IPv6 Fragmentation Considered Ineffective" Deprecation =========== All instances of the word "deprecate" should be removed from the document. Therefore: -- The document should not request any IANA actions -- The document doesn't UDPDATE 2460 -- The document doesn't need to be PS. BCP is good enough Recommendation =============== The Recommendation section should be renamed "Conclusion". It should include the following statements: - The IETF SHOULD NOT standardize an new protocols that rely on IPv6 fragmentation ---*New* applications and transport layer protocols SHOULD support effective PLMTUD [RFC4821] since ICMP-based PMTUD [RFC1981] is unreliable --*New* applications or transport layer protocols that cannot support effective PMTUD MUST NOT in any circumstances send IPv6 packets that exceed the IPv6 minimum MTU of 1280 bytes. - Legacy applications and transport layer protocols will continue to generate fragments --- In the interest of backwards compatibility, IPv6 stacks and forwarding nodes MUST continue to support inbound fragmented IPv6 packets as specified in [RFC2460]. - Implementers and operators need to be aware that on many paths through the Internet, IPv6 fragmentation will fail. Legacy applications and transport layer protocols that do not conform to the previous paragraph can expect connectivity failures as a result. --- Therefore, if a legacy protocol is capable of breaking its dependence on IPv6 fragmentation, it should consider doing so. Did I miss anything?
