RFC 4821 PMTUD is that "negotiation" that is "lacking". It is there. It is deployed. It actually works. No more relying on someone sending the ICMP packets through in order for PMTUD to work!
For some value of "works". There are way too many places filtering ICMP for PMTUD to work consistently. PMTUD is *not* the solution, unfortunately. Steinar Haug, Nethelp consulting, sthaug@nethelp.no
