Revision to Registration Procedures for IS-IS Neighbor Link-Attribute
                              Bit Values

Abstract

  RFC 5029, "Definition of an IS-IS Link Attribute Sub-TLV", defines an
  IANA registry called "IS-IS Neighbor Link-Attribute Bit Values".
  This document changes the registration procedure for that registry
  from "Standards Action" to "Expert Review".  This document updates
  RFC 5029.

1.  Introduction

  [RFC5029] defines the "IS-IS Neighbor Link-Attribute Bit Values"
  registry and specifies a registration procedure of "Standards
  Action".  In practice, this registration procedure is unnecessarily
  restrictive, as it prevents allocation of bits to experimental
  protocols, which in turn increases the risk of conflicts introduced
  by use of unregistered code points (so-called "code point
  squatting").

  Accordingly, this document changes the registration procedure for the
  registry, as described in Section 2.

2.  IANA Considerations

  IANA has changed the registration procedure for the "IS-IS Neighbor
  Link-Attribute Bit Values" registry to "Expert Review" [RFC8126] and
  has listed this document as a reference for the registry.  General
  guidance for the designated experts is defined in [RFC7370], and more
  specific guidance can be found in [RFC5029].

3.  Security Considerations

  This document does not affect the security issues discussed in
  [RFC5029].
