Dan, There must have been a confusion: I am AGAINST IPv6 PTB messages with MTU<1280. (Your last message, addressed to both Fred and me suggests you believe I support them.)
My personal point is AGAINST networks purposely losing "normal" PTB error messages, i.e. with MTB>1280. Considering that these losses become a MAY, even in IPv6, just because it is believed that some networks lose them would be IMHO a mistake, at least without a good understanding of where and why it is done.

AFAIK it is not written anywhere that networks are authorized to do otherwise. _______________________________________________ Softwires mailing list [email protected] https://www.ietf.org/mailman/listinfo/softwires
