This document makes several erroneous assumptions, IMO: - 2.2: applications don't "tailor the MSS" (transport layers do)
- overall: PMTUD is deprecated, in favor of PLMTUD -overall: in a tunneling system, the packetization layer is the tunnel encapsulator, which means that layer should be doing MTU discovery - 3.1: PTB ICMPs are generated when the packet size is greater than the link MTU, not the other way around - 3.1: IPv6 doesn't have a DF bit - the overall approach misuses DF and PTB messages, IMO These issues have been discussed repeatedly on the INTAREA mailing list.
