Abstract

   This document recommends that network implementors who have planned
   or deployed an OSI NSAP addressing plan, and who wish to deploy or
   transition to IPv6, should redesign a native IPv6 addressing plan to
   meet their needs.  However, it also defines a set of mechanisms for
   the support of OSI NSAP addressing in an IPv6 network.  These
   mechanisms are the ones that MUST be used if such support is
   required.  This document also defines a mapping of IPv6 addresses
   within the OSI address format, should this be required.
