Abstract
This memo reclassifies RFC 1142, "OSI IS-IS Intra-domain Routing
Protocol", to Historic status. This memo also obsoletes RFC 1142.

1. Introduction
IS-IS is the "OSI Intermediate system to Intermediate system intra-
domain routeing information exchange protocol for use in conjunction
with the protocol for providing the connectionless-mode Network
Service (ISO 8473)", otherwise known as ISO/IEC 10589. It has been
extended for use with IP by RFC 1195 [RFC1195] and subsequently
enhanced by many other RFCs.
RFC 1142 [RFC1142] was a republication of ISO DP 10589 originally
provided as a service to the Internet community. However, ISO DP
10589 was an ISO "Draft Proposal", which differed in a considerable
number of significant respects from the final standardized version
published as ISO/IEC 10589 [ISO10589-First-Edition], and subsequently
revised as ISO/IEC 10589 Second Edition [ISO10589-Second-Edition].
It has been an ongoing source of confusion when RFC 1142 has been
unwittingly quoted or referenced in place of ISO/IEC 10589 itself.
All references to IS-IS should be to the latest edition of the IS-IS
standard (currently ISO/IEC 10589:2002, Second Edition), and RFC 1142
is only of historic interest.
This memo explains why RFC 1142, "OSI IS-IS Intra-domain Routing
Protocol", is reclassified to Historic status. This memo also
obsoletes RFC 1142.
2. Security Considerations
Reclassifying RFC 1142 has no security considerations.

§1IS-IS and ISO/IEC 10589
IS-IS is the OSI Intermediate System to Intermediate System intra-domain routing protocol, also known as ISO/IEC 10589. RFC 1195 extended it for use with IP, and later RFCs added enhancements.
The memo says references to IS-IS should point to the latest edition of the IS-IS standard.
IS-IS is a routing protocol defined by an ISO/IEC standard. Other RFCs describe its use with IP and later enhancements.
§1Why RFC 1142 Caused Confusion
RFC 1142 republished ISO DP 10589 for the Internet community. ISO DP 10589 was a Draft Proposal and differed in significant ways from the final standardized ISO/IEC 10589, which was later revised as a Second Edition.
The memo says RFC 1142 was sometimes unwittingly quoted or referenced instead of the final ISO/IEC standard.
RFC 1142 contained a draft that differed from the final standard. Citing the draft as if it were the final version caused confusion.
§2Reclassification to Historic
RFC 7142 obsoletes RFC 1142 and reclassifies it to Historic. The memo says RFC 1142 is only of historic interest and names ISO/IEC 10589:2002, Second Edition, as the current edition at the time.
The RFC states that reclassification has no security considerations.
RFC 1142 should no longer be used as the definition of IS-IS. This memo directs readers to the current ISO/IEC 10589 edition instead.
