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.

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]. 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Type | Length | Sub-Type | NAI ... +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Type (Type to be assigned by IANA) (skippable) [3] Length The length of the NAI field Sub-Type This field describes the type of the entity which owns the NAI. NAI MKhalil, Qaddoura, Akhtar, Calhoun [Page 2] INTERNET DRAFT February 2000 Contains the NAI [2] in a string format. 2.1 Mobile Node NAI Extension The Mobile Node NAI Extension is subtype 1 of the Generalized NAI extension (see section 2.0) and contains the Mobile Node's NAI. This extension can be found in a Registration Request or Reply [3]. 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Type | Length | Sub-Type | MN-NAI ... +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Type (Same type value as section 2.0) (skippable) [3] Length The length of the NAI field Sub-Type 1 MN-NAI Contains the NAI [2] of the Mobile Node. 2.2 Foreign Agent NAI Extension The Foreign Agent NAI Extension is subtype 2 of the Generalized NAI extension (see section 2.0) and contains the Foreign Agent's NAI. This extension can be found in a Registration Request or Reply [3]. 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Type | Length | Sub-Type | FA-NAI ... +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Type (Same type value as section 2.0) (skippable) [3] MKhalil, Qaddoura, Akhtar, Calhoun [Page 3] INTERNET DRAFT February 2000 Length The length of the NAI field Sub-Type 2 FA-NAI Contains the Foreign Agent's NAI [2]. 2.3 Home Agent NAI Extension The Home Agent NAI Extension is subtype 3 of the Generalized NAI extension (see section 2.0) and contains the Home Agent's NAI. This extension can be found in a Registration Request or Reply [3]. 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Type | Length | Sub-Type | HA-NAI ... +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Type (Same type value as section 2.0) (skippable) [3] Length The length of the NAI field Sub-Type 3 HA-NAI Contains the Home Agent's NAI [2]. 2.4 Previous Foreign Agent NAI Extension The Previous Foreign Agent NAI Extension is subtype 4 of the Generalized NAI extension (see section 2.0) and contains the Previous Foreign Agent's NAI. This extension can be found in a Registration Request or Reply [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]. 4.0 References [1] Calhoun, Perkins.
