Hi all;

Just a procedural question.

Though rfc2026 says:

    A specification for which significant implementation and successful
    operational experience has been obtained may be elevated to the
    Internet Standard level.  An Internet Standard (which may simply be
    referred to as a Standard) is characterized by a high degree of
    technical maturity and by a generally held belief that the specified
    protocol or service provides significant benefit to the Internet
    community.

does rfc1981bis qualify?

It seems to me that rfc1981 operationally failed and rfc4821 was
developed, which means PMTUD can be IS only when rfc4821 become IS.

Or, do I misunderstand something?
