THIS IS A TEMPORARY FILE
MOBILE IP NUMBERS
The document "IP Mobility Support" [RFC 2002] specifies some message
types and extensibility fields.
Two separately maintained sets of numbering spaces, from which
Extension Type values are allocated, are used in Mobile IP:
The first set consists of those Extensions which may appear only
in Mobile IP control messages (those sent to and from UDP port
number 434). Currently, the following Types are defined for
Extensions appearing in Mobile IP control messages:
Value Name Reference
----- -------------------------------------- ---------
32 Mobile-Home Authentication
33 Mobile-Foreign Authentication
34 Foreign-Home Authentication
36 Generalized Mobile IP Authentication [RFC3012]
38 Critical Vendor/Organization Specific Extension(CVSE) [RFC3025]
128 Integrated Mobility Extension [Solomon]
129 Traversal Extension [Montenegro]
130 Encapsulating Delivery Style Extension [RFC2344]
131 Mobile Node NAI [RFC2794]
134 Normal Vendor/Organization Specific Extension (NVSE) [RFC3025]
The second set consists of those extensions which may appear only
in ICMP Router Discovery messages [4]. Currently, Mobile IP
defines the following Types for Extensions appearing in ICMP
Router Discovery messages:
Value Name Reference
----- ------------------------------------------ ---------
0 One-byte Padding (encoded with no Length nor Data field)
16 Mobility Agent Advertisement
19 Prefix-Lengths
24 Challenge [RFC3012]
132 MN-FA Challenge Extension [RFC3012]
Due to the separation (orthogonality) of these sets, it is
conceivable that two Extensions that are defined at a later date
could have identical Type values, so long as one of the Extensions
may be used only in Mobile IP control messages and the other may be
used only in ICMP Router Discovery messages.
When an Extension numbered in either of these sets within the range
0 through 127 is encountered but not recognized, the message
containing that Extension MUST be silently discarded. When an Extension
numbered in the range 128 through 255 is encountered which is not
recognized, that particular Extension is ignored, but the rest of
the Extensions and message data MUST still be processed. The
Code Field
The following values are defined for use within the Code field.

0 registration accepted
1 registration accepted, but simultaneous mobility
bindings unsupported

72 requested encapsulation unavailable
73 requested Van Jacobson compression unavailable
74 request reverse tunnel unavailable [RFC2344]

97 missing_nai [RFC2794]
98 missing_home_agent [RFC2794]

102-103 unassigned
104 unknown_challenge [RFC3012]
105 missing_challenge [RFC3012]
106 stale_challenge [RFC3012]
Registration denied by the home agent:
128 reason unspecified
129 administratively prohibited
130 insufficient resources
131 mobile node failed authentication
132 foreign agent failed authentication
133 registration Identification mismatch
134 poorly formed Request
135 too many simultaneous mobility bindings

139 requested encapsulation unavailable [RFC2344]
140 ERROR-HA-1 [RFC3025]
141 ERROR-HA-2 [RFC3025]
SPI Values for the Mobile IP Reserved SPIs
0 Reserved [RFC3012]
1 Reserved [RFC3012]
2 CHAP [RFC3012]
Generalized Authentication Extension - Subtypes
1 MN-AAA Authentication subtype [RFC3012]
