"North-Bound Distribution of Link-State and Traffic Engineering (TE) Information Using BGP" [RFC 7752
] requested IANA to create a registry called "Border Gateway Protocol - Link State (BGP-LS) Parameters" with a number of subregistries. The allocation policy applied by IANA for those registries is "Specification Required", as defined in [RFC 8126
The "Specification Required" policy requires evaluation of any assignment request by a "designated expert", and guidelines for any such experts are given in Section 5.1
of RFC 7752
. In addition, this policy requires that "the values and their meanings must be documented in a permanent and readily available public specification, in sufficient detail so that interoperability between independent implementations is possible" [RFC 8126
]. Further, the intention behind "permanent and readily available" is that "a document can reasonably be expected to be findable and retrievable long after IANA assignment of the requested value" [RFC 8126
Another allocation policy called "Expert Review" is defined in [RFC 8126
]. This policy also requires Expert Review but has no requirement for a formal document.
All reviews by designated experts are guided by advice given in the document that defined the registry and set the allocation policy.
This document updates [RFC 7752
] by changing the allocation policy for all of the registries to "Expert Review" and updating the guidance to the designated experts.
The key words "MUST
", "MUST NOT
", "SHALL NOT
", "SHOULD NOT
", "NOT RECOMMENDED
", and "OPTIONAL
" in this document are to be interpreted as described in BCP 14 [RFC 2119
] [RFC 8174
] when, and only when, they appear in all capitals, as shown here.
