IMHO it's better to have an informational RFC that says "if you obey these simple formatting rules, your packet is likely to be transported (fast)" than nothing at all. I just searched draft-ietf-v6ops-6204bis-12 for requirements on extension headers. Nada AFAICS. I also just tested my own home CPE for outbound transmission of extension headers (with and without firewall configured): HBH EH: tick Destination Options EH: tick Fragment EH: looks like they're always dropped regards, RayH -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
