Updates to the IS-IS TLV Codepoints Registry
Abstract
This document recommends some editorial changes to the IANA "IS-IS

1. Introduction
The "IS-IS TLV Codepoints" registry was created by [RFC3563] and
extended by [RFC6233]. The assignment policy for the registry is
"Expert Review" as defined in [RFC5226]. As documents related to
IS-IS are developed, the codepoints required for the protocol
extensions are reviewed by the Designated Experts and added to the
IANA-managed registry. As these documents are published as RFCs, the
registries are updated to reference the relevant RFC.
In the case of TLVs supporting prefix advertisement, currently
separate sub-TLV registries are maintained for each TLV. These
registries need to be combined into a common sub-TLV registry similar
to what has been done for neighbor advertisement TLVs.
In some cases, there is a need to allocate codepoints defined in
Internet-Drafts (I-Ds) that seem likely to eventually gain Working
Group approval, without waiting for those I-Ds to be published as
RFCs. This can be achieved using Expert Review, and this document
