[RFC5029] defines the "IS-IS Neighbor Link-Attribute Bit Values"registry and specifies a registration procedure of "StandardsAction". In practice, this registration procedure is unnecessarilyrestrictive, as it prevents allocation of bits to experimentalprotocols, which in turn increases the risk of conflicts introduced byuse of unregistered code points (so-called "code point squatting").¶
Accordingly, this document changes the registration procedure for theregistry, as described inSection 2.¶
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 guidancefor the designated experts is defined in[RFC7370], and more specificguidance can be found in[RFC5029].¶
