Abstract

This document recommends that RFC 1888, on Open Systems Interconnection (OSI) Network Service Access Points (NSAPs) and IPv6, be reclassified as Historic, as most of it has no further value, apart from one section, which is faulty.

1.  Introduction

   [RFC1888] was published as an Experimental RFC in 1996, at an early
   stage in the development of IPv6, when it appeared important to
   consider usage of Open Systems Interconnection (OSI) addressing for
   IPv6.  In Sections 3 through 5, it defines mappings of certain OSI
   Network Service Access Point (NSAP) addresses inside IPv6 addresses,
   and how to carry arbitrary NSAP addresses as IPv6 destination
   options.  However, it also contains significant "health warnings"
   about the difficulty of routing packets in the global Internet using
   such addresses.  As far as is known to the IETF, these address
   mappings have never been seriously used and are not supported by IPv6
   implementations.  Furthermore, the deployment of OSI solutions is not

   sufficiently widespread that any change in this situation can be
   expected.

   Additionally, Section 6 of [RFC1888] specifies a mapping of IPv6
   addresses inside OSI NSAP addresses.  This mapping has recently
   aroused some interest: for example, to allow IP addresses to be
   expressed in an Asynchronous Transfer Mode (ATM) context.
   Unfortunately, Section 6 of [RFC1888] contains two e...
