For those who aren't following the routing & addressing discussions, there's been some discussion on MTU size issues and tunnel-based solutions. See below, but it did strike me that 2460 doesn't *explicitly* say "don't send more than 1280 bytes unless you determine that a larger MTU will work." It's implied but not stated.

I just re-read RFC 2460 section 5. Admittedly things are less clear for IPv4, but it seems clear that IPv6 senders should not exceed 1280 bytes (pre-encapsulation) unless they have succeeded in discovering a larger path MTU.
Nice to hear some good news for a change. ;-) Thanks, Dino -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
