 Guidelines and Registration Procedures for Interface Types and Tunnel

Abstract

   This document provides guidelines and procedures for those who are
   defining, registering, or evaluating definitions of new interface
   types ("ifType" values) and tunnel types.  The original definition of
   the IANA interface type registry predated the use of IANA
   Considerations sections and YANG modules, and so some confusion arose
   over time.  Tunnel types were added later, with the same requirements
   and allocation policy as interface types.  This document updates RFC
   2863, and provides updated guidance for these registries.

1.  Introduction

   The IANA IfType-MIB, which contains the list of interface type
   (ifType) values, was originally defined in [RFC1573] as a separate
   MIB module together with the Interfaces Group MIB (IF-MIB) module.
   The IF-MIB module was subsequently updated and is currently specified
   in [RFC2863], but this latest IF-MIB RFC no longer contains the IANA
   IfType-MIB.  Instead, the IANA IfType-MIB is maintained by IANA as a
   separate module.  Similarly, [RFC7224] created an initial IANA
   Interface Type YANG Module, and the current version is maintained by
   IANA.

   The current IANA IfType registry is at [ifType-registry], with the
   same values also appearing in both [yang-if-type] and the IANAifType
   textual convention at [IANAifType-MIB].

   Although the ifType registry was originally defined in a MIB module,
   the assignment and use of interface type values are not tied to MIB
