For a tunnel protocol it is the tunnel protocol implementation that needs either implicitly or explicitly indicate or signal that it will use zero checksum for a particular flow or ports. > If yes, signal from where to whom? > Or maybe by "implementation" you mean "IPv6 protocol stack > implementation" The protocol or implementation using zero checksum is the one that needs to signal it. But from my perspective it can be dealt with implicitly in some cases where static ports works.

Yes, we can add that as a existing cause for packets with erronous source address to be dropped. cheers Magnus Westerlund ---------------------------------------------------------------------- Multimedia Technologies, Ericsson Research EAB/TVM ---------------------------------------------------------------------- Ericsson AB | Phone +46 10 7148287 Färögatan 6 | Mobile +46 73 0949079 SE-164 80 Stockholm, Sweden| mailto: magnus.westerl...@ericsson.com ---------------------------------------------------------------------- -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
