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].
