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.

rfc-5029 — Definition of an IS-IS Link Attribute Sub-TLV

Extracted elements (3)

design-rationale §1

The original 'Standards Action' registration procedure was unnecessarily restrictive because it prevented allocation of bits to experimental protocols, increasing the risk of 'code point squatting' (use of unregistered code points that may later conflict with standardized assignments). Relaxing to 'Expert Review' mitigates this risk.

registry §2

The 'IS-IS Neighbor Link-Attribute Bit Values' registry, originally defined in RFC 5029, has its registration procedure changed from 'Standards Action' to 'Expert Review' by this document. General guidance for designated experts is defined in RFC 7370, with more specific guidance in RFC 5029.

security-consideration §3

This document does not affect the security issues discussed in RFC 5029. The change in registration procedure from 'Standards Action' to 'Expert Review' has no security impact beyond what was already addressed in the original specification.
