RFC 7142RFC 1142 to Historic             February 20141.  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 byRFC 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 whenRFC 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), andRFC 1142   is only of historic interest.   This memo explains whyRFC 1142, "OSI IS-IS Intra-domain Routing   Protocol", is reclassified to Historic status.  This memo also   obsoletesRFC 1142.2.  Security Considerations   ReclassifyingRFC 1142 has no security considerations.3.  References3.1.
