The following errata report has been held for document update for RFC9350, "IGP Flexible Algorithm".
-------------------------------------- You may review the report below and at: https://www.rfc-editor.org/errata/eid7376 -------------------------------------- Status: Held for Document Update Type: Editorial Reported by: Nikolai Malykh <nmal...@protokols.ru> Date Reported: 2023-03-04 Held by: John Scudder (IESG) Section: 6 Original Text ------------- One of the limitations of IS-IS [ISO10589] is that the length of a TLV/sub-TLV is limited to a maximum of 255 octets. For the FAD sub- TLV, there are a number of sub-sub-TLVs (defined below) that are supported. For a given Flex-Algorithm, it is possible that the total number of octets required to completely define a FAD exceeds the maximum length supported by a single FAD sub-TLV. In such cases, the FAD MAY be split into multiple such sub-TLVs, and the content of the multiple FAD sub-TLVs are combined to provide a complete FAD for the Flex-Algorithm. In such a case, the fixed portion of the FAD (see Section 5.1) MUST be identical in all FAD sub-TLVs for a given Flex- Algorithm from a given IS.

Notes ----- Although "IS" is listed in https://www.rfc-editor.org/materials/abbrev.expansion.txt as well-known, this evidently confused at least one reader, so it seems worth expanding on first use.
