Re: re: -1.4%
IIRC, IPv6 won't fragment like IPv4, so if you hit a router with a pants MTU, you're worse off.
Minimum MTU for IPv6 is 1280 bytes. Most software is written to assume an MTU of 500 bytes, and most equipment can handle at least 1492 bytes.
I'd say the router with the "pants MTU" would soon be replaced if it stopped working due to these requirements.
