Abstract

   RFC 1264 was written during what was effectively a completely
   different time in the life of the Internet.  It prescribed rules to
   protect the Internet against new routing protocols that may have
   various undesirable properties.  In today's Internet, there are so
   many other pressures against deploying unreasonable protocols that we
   believe that existing controls suffice, and the RFC 1264 rules just
   get in the way.

1.  Introduction

   RFC 1264 [RFC1264] describes various rules to be applied when
   publishing routing protocols on the IETF Standards Track, including
   requirements for implementation, MIBs, security, etc.  These rules
   were written in an attempt to protect the Internet from incomplete or
   unscalable new protocols.

   Today, one of the big problems the IETF faces is timeliness.
   Applying additional rules to a certain class of protocols hurts the
   IETF's ability to publish specifications in a timely manner.

   The current standards process [RFC2026] already permits the IESG to
   require additional implementation experience when it appears to be
   needed.  We do not need any more rules than that.  RFC 2026 says:

      Usually, neither implementation nor operational experience is
      required for the designation of a specification as a Proposed
      Standard.  However, such experience is highly desirable, and will
      usually represent a strong argument in favor of a Proposed
      Standard designation.

      The IESG may require implementation and/or operational experience
      prior to granting Proposed Standard status to a specification that
      materially affects the core Internet protocols or that specifies
      behavior that may have significant operational impact on the
      Internet.

2.  RFC 1264 Is Obsolete

   Therefore, this document reclassifies RFC 1264 as historic.  While
   that does not prohibit the Routing Area Directors from requiring
   implementation and/or operational experience under the RFC 2026
   rules, it removes the broad, general requirement from all routing
   documents.

3.  Working Group Procedures

   Some working groups within the Routing Area have developed
   procedures, based on RFC 1264, to require implementations before
   forwarding a document to the IESG.  This action does not prevent
   those working groups from continuing with these procedures if the
   working group prefers to work this way.  We encourage working groups
   to put measures in place to improve the quality of their output.

   RFC 1264 required a MIB module to be in development for a protocol;
   this is still encouraged in a broad sense.  This is not meant to be
   limiting, however; protocol management and manageability should be
   considered in the context of current IETF management protocols.  In
   addition, [RTG-REQS] contains a description of a "Manageability
   Requirements" section; this is not currently a requirement but should
   be considered.

4.  Security Considerations

   While RFC 1264's rules placed additional constraints on the
   security-related contents of an RFC, current policies (e.g., the
   requirement for a Security Considerations section) suffice.

5.  Acknowledgements

   Alex Zinin and Bill Fenner spent a great deal of time trying to
   produce an updated version of the RFC 1264 rules that would apply to
   today's Internet.  This work was eventually abandoned when it was
   realized (after much public discussion at Routing Area meetings,
   Internet Area meetings, and on the Routing Area mailing list) that
   there was just no way to write the rules in a way that advanced the
   goals of the IETF.

PROBLEMRFC 1264 imposed extra requirements (implementation, MIBs, security) on routing protocols seeking the IETF Standards Track, which slowed publication.
MECHANISMRFC 4794 reclassifies RFC 1264 as Historic, leaving the general rules of RFC 2026, under which the IESG can already require implementation experience.
WHY IT MATTERSThe blanket requirement for all routing documents is gone. Working groups may keep their own stricter procedures.

§1What RFC 1264 Required

RFC 1264 described rules for publishing routing protocols on the IETF Standards Track, including requirements for implementation, MIBs and security. They were written to protect the Internet from incomplete or unscalable new protocols.

The author says RFC 1264 was written during what was effectively a completely different time in the life of the Internet. Today there are so many other pressures against deploying unreasonable protocols that existing controls suffice, and the rules just get in the way.

Long ago, routing protocols had to pass an extra inspection. Now there are many other reasons nobody would use a bad one, so the extra inspection just slows things down.

§2Why It Is Obsolete

The memo names timeliness as one of the big problems the IETF faces, and says extra rules for one class of protocols hurt the ability to publish on time. The standard process in RFC 2026 already lets the IESG require implementation and/or operational experience for a Proposed Standard that materially affects core Internet protocols or has significant operational impact.

The document therefore reclassifies RFC 1264 as historic. The Routing Area Directors can still require such experience under RFC 2026, but the broad, general requirement on all routing documents is removed. The authors had tried to write an updated version of the rules and abandoned the effort when they concluded there was no way to write them so that they advanced the IETF's goals.

The general rule book already lets the referee ask for proof when it matters. So a second rule book just for routing is dropped.

§3Working Groups and Manageability

Some Routing Area working groups developed procedures based on RFC 1264, such as requiring implementations before sending a document to the IESG. This action does not stop them from continuing, and the memo encourages working groups to put measures in place to improve the quality of their output.

RFC 1264 required a MIB module to be in development. That is still encouraged in a broad sense, but manageability should be considered in the context of current IETF management protocols. A "Manageability Requirements" section is described in a work-in-progress draft; it is not currently a requirement but should be considered. For security, current policies such as the requirement for a Security Considerations section suffice.

Teams that like the old checks may keep them. Thinking about how to look after your protocol is still a good idea, but it is no longer a must.
