LSR Working Group 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".

Introduction 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 .

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 .

Security Considerations This document does not affect the security issues discussed in RFC 5029.
