Internet Engineering Task Force T.Przygienda INTERNET DRAFT Redback July 2001 Reserved TLV Codepoints in ISIS <draft-ietf-isis-wg-tlv-codepoints-00.txt> Status of This Memo This document is an Internet-Draft and is in full conformance with all provisions of Section 10 of RFC2026. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress."

Abstract This draft describes implementation codepoints within IS-IS [ISO90 , Cal90a , Cal90b ] 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 IGP. This draft summarizes all TLV codepoints that are being used by the protocol and its pending extensions. Przygienda Expires Jan 2002 [Page 1] Internet Draft TLV Codepoints July 2001 1.

Assignment Procedures This document is provided to avoid possible future conflicts in 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, Przygienda Expires Jan 2002 [Page 2] Internet Draft TLV Codepoints July 2001 no plausible central authority to assign TLV numbers exists as of today. 3.
