 Revision to Registration Procedures for IS-IS Neighbor Link-Attribute
                               Bit Values
                  draft-ietf-lsr-labv-registration-03

Abstract

   RFC 5029, "Definition of an IS-IS Link Attribute Sub-TLV", defines a
   registry for "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
   RFC5029.

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

   The registration procedure for the "IS-IS Neighbor Link-Attribute Bit
   Values" registry is changed to be "Expert Review".  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 RFC
   5029.
