    Revision to Registration Procedures for Multiple BMP Registries

Abstract

   This document updates RFC 7854, "BGP Monitoring Protocol (BMP)", by
   changing the registration procedures for several registries.
   Specifically, any BMP registry with a range of 32768-65530 designated
   "Specification Required" has that range redesignated as "First Come
   First Served".

1.  Introduction

   [RFC7854] creates a number of IANA registries that include a range of
   32768-65530 designated "Specification Required".  Each such registry
   also has a large range designated "Standards Action".  Subsequent
   experience has shown two things.  First, there is less difference
   between these two policies in practice than there is in theory
   (consider that [RFC8126] explains that for Specification Required,
   "Publication of an RFC is an ideal means of achieving this
   requirement").  Second, it's desirable to have a very low bar to
   registration, to avoid the risk of conflicts introduced by use of
   unregistered code points (so-called "code point squatting").

   Accordingly, this document revises the registration procedures, as
   given in Section 2.

2.  IANA Considerations

   IANA has revised the following registries within the BMP group:

   *  BMP Statistics Types
   *  BMP Initiation and Peer Up Information TLVs
   *  BMP Termination Message TLVs
   *  BMP Termination Message Reason Codes
   *  BMP Route Mirroring TLVs
   *  BMP Route Mirroring Information Codes

   For each of these registries, the ranges 32768-65530 whose
   registration procedures were "Specification Required" are revised to
   have the registration procedures "First Come First Served".

3.  Security Considerations

   This revision to registration procedures does not change the
   underlying security issues inherent in [RFC7854].

PROBLEMBGP Monitoring Protocol (BMP) registries had strict registration rules (Specification Required) for code points 32768-65530, which delayed allocation and increased the risk of unregistered code points being used informally.
MECHANISMRFC 9515 changes six BMP registries so that the 32768-65530 range uses First Come First Served instead of Specification Required, allowing faster allocation with minimal review.
WHY IT MATTERSNetwork operators can now quickly register new monitoring extensions without waiting for RFC approval, reducing pressure to use unregistered code points.

§1The Problem

RFC 7854 created the BGP Monitoring Protocol (BMP) and defined several IANA registries for code points. These registries included two ranges: one requiring Specification Required (strict approval) and another requiring Standards Action (full RFC process). In practice, the high-value range 32768-65530 with Specification Required was almost never used because the burden of getting a specification published was too high.

This created pressure for operators to use unregistered code points unofficially, risking collisions when multiple vendors independently chose the same values.

There was a waiting list to add new things, and the waiting process was so strict that nobody used it officially. People started using secret code points instead.

§2First Come First Served Registration

RFC 9515 changes six registries: BMP Statistics Types, Initiation and Peer Up TLVs, Termination Message TLVs, Termination Message Reason Codes, Route Mirroring TLVs, and Route Mirroring Information Codes. For each registry, the 32768-65530 range now uses First Come First Served instead of Specification Required.

First Come First Served is a registration policy defined in RFC 8126 that requires only basic checks (is the code point available? does the request make sense?) and does not require publication of an RFC or specification.

Instead of saying yes or no to formal applications, the registrar now just checks if the number is free and approves it. It takes minutes instead of months.

§3Impact on Network Monitoring

This change makes BMP more useful for proprietary and experimental extensions. Organizations can now quickly reserve code points for their own monitoring probes or for features still in development. The lower bar for registration is balanced by keeping the highest ranges (Standards Action) for features that must be widely interoperable.

Network teams can now try new monitoring ideas without waiting for approval committees. When an idea proves useful, it can still be formalized later.
