I have read this draft. Isn't the obvious brute force mitigation to clamp all of your DC to IPv6 minimum MTU? And isn't it yet another hint that PMTUD really needs to be incorporated into the transport layer [if we needed another]? e.g. by referencing Packetization Layer Path MTU Discovery (PLPMTUD) http://tools.ietf.org/html/rfc4821 That should also be handled correctly by the load balancers, or not? -- Regards, RayH
