Abstract

   The Mobile IP Extensions Rationalization (MIER) specification defines
   a new extension header format, that is intended to extend the Mobile
   IP extension address space. This document defines the Generalized
   Network Access Identifier (NAI) extension, which SHOULD be used by
   any Mobile IP extension specifying an extension containing an NAI.

1.0 Introduction

   The Mobile IP Extensions Rationalization (MIER) specification [10]
   defines a new extension header format, that is intended to extend the
   Mobile IP extension address space. This document defines the
   Generalized Network Access Identifier (NAI) [2] extension, which
   SHOULD be used by any Mobile IP extension specifying an extension
   containing an NAI.


2.0  Generalized NAI Extension

   This section defines the generalized NAI Extension, used by any
   extension that must carry data in the format of an NAI [2].

           excluding the extension Type and the extension Length fields.
           This field MUST be set to 1 plus the total length of the 
           NAI field.

   Sub-Type

      This field describes the type of the entity which owns the NAI.

3.0  IANA Considerations

   The value for the "Generalized NAI Extension" in section 2.0 (and
   used in sections 2.1 through 2.4) must be assigned from the numbering
   space defined for Mobile IP registration extensions as defined in RFC
   2002 [3]. These MUST NOT conflict with any numbers used in RFC
   2002[3], RFC 2344 [5], RFC 2356 [6], Mobile IP Challenge/Response
   Extensions Draft [7], Mobile IP Network Access Identifier Extensions
   Draft[1], or Mobile IP Based Micro Mobility Management Protocol in
   The Third Generation Wireless Network Draft [8].
