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.
