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.

1. General recommendation on NSAP addressing plans

This recommendation is addressed to network implementors who have

already planned or deployed an OSI NSAP addressing plan for the usage

of OSI CLNP [IS8473] according to the OSI network layer addressing

plan [IS8348] using ES-IS and IS-IS routing [IS9542, IS10589]. It

recommends how they s...
