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.

2. 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,

no plausible central authority to assign TLV numbers exists as of
today.
