What we lack is a fix for the freeloader problem. Other than declaring TCP MD5 a hazard and actively abandoning it, there’s too much of a fallback. One step might be for the IETF to prohibit support for TCP MD5 in all new work - e.g., there’s pending work in TCPM to develop a YANG model that includes MD5 “for legacy support”, but that only serves to feed the problem. But a new solution isn’t going to make freeloading easier. Joe -- last-call mailing list last-call@xxxxxxxx https://www.ietf.org/mailman/listinfo/last-call
