Folks, FYI: <http://www.ietf.org/internet-drafts/draft-gont-v6ops-ipv6-ehs-in-real-world-00.txt>. Comments welcome. Thanks! Fernando -------- Forwarded Message -------- Subject: New I-D: IPv6 Extension Headers in the Real World Date: Fri, 08 Aug 2014 00:04:37 -0400 From: Fernando Gont <fgont@si6networks.com> To: IPv6 Operations <v6ops@ietf.org> Folks, We have published a new I-D on the topic of IPv6 Extension Headers (EHs). The I-D is available at: <http://www.ietf.org/internet-drafts/draft-gont-v6ops-ipv6-ehs-in-real-world-00.txt>. Abstract: IPv6 Extension Headers allow for the extension of the IPv6 protocol, and provide support for some core functionality such as IPv6 fragmentation. However, IPv6 Extension Headers are deemed to present a challenge to IPv6 implementations and networks, and are known to be intentionally filtered in some existing IPv6 deployments. This summarizes the issues associated with IPv6 extension headers, and presents real-world data regarding the extent to which packets with IPv6 extension headers are filtered in the public Internet, and where in the network such filtering occurs. Additionally, it provides some guidance to operators in troubleshooting IPv6 blackholes resulting from the use of IPv6 extension headers. Finally, this document provides some advice to protocol designers, and discusses areas where further work might be needed. Comments and suggestions are welcome. Thanks!
