Abstract
摘要
This document describes implementation codepoints within Intermediate System to Intermediate System (IS-IS) used today by several ISPs for routing within their clouds. IS-IS is an interior gateway routing protocol developed originally by OSI and used with IP extensions as Interior Gateway Protocol (IGP). This document summarizes all Table, Length and Value (TLV) codepoints that are being used by the protocol and its pending extensions.
本文档描述了中间系统到中间系统（IS-IS）中的实现代码点，这些代码点目前被一些ISP用于在其云中进行路由。IS-IS是最初由OSI开发的内部网关路由协议，与IP扩展一起用作内部网关协议（IGP）。本文档总结了协议及其待定扩展正在使用的所有表、长度和值（TLV）代码点。

This document is provided to avoid possible future conflicts in the assignment of TLV numbers. It does not constitute or represent any standard or authority assigning TLV numbers. TLV assignment happens on a shared, informational basis between the ISO, SIF and the IETF working groups. The core ISIS protocol is being specified in the ISO standards body, IP extensions to it however are products of the ISIS working group in IETF. Since ISO does not provide a numbering authority and IANA is only responsible for IP related coding points, no plausible central authority to assign TLV numbers exists as of today.
提供本文件是为了避免TLV编号分配中可能出现的未来冲突。它不构成或代表分配TLV编号的任何标准或机构。TLV分配在ISO、SIF和IETF工作组之间共享信息的基础上进行。核心ISIS协议由ISO标准机构规定，但其IP扩展是IETF中ISIS工作组的产品。由于ISO不提供编号机构，IANA仅负责与IP相关的编码点，因此到目前为止，还不存在分配TLV编号的合理中央机构。
This document will be periodically updated by newer versions in the fashion of [RP94] and successors. It may be replaced at any given point in time by some type of official registry.
本文件将以[RP94]和后续版本的形式定期更新。它可以在任何特定时间点被某种形式的官方登记所取代。
This document will not indicate specific documents using the codepoints, nor will it resolve the sub-TLV codepoints.
本文件不会指明使用代码点的特定文件，也不会解析子TLV代码点。
