5. IANA Considerations
The Internet Assigned Numbers Authority (IANA) has been and continues to be responsible for maintaining the ADDRESS FAMILY NUMBERS (http://www.isi.edu/in-notes/iana/assignments/address-family-numbers) name space assignments. The IANA has placed this list in a MIB module, such that it may be imported into other MIBs. The motivation for doing this is to allow MIBs to not have to change when a new assignment is made to the ADDRESS FAMILY NUMBERS. This is very similar to the motivation behind the IANAifType-MIB. Any additions or changes to the list of ADDRESS FAMILY NUMBERS registered via IANA will be done as they have in the past and this document does not propose any changes to the ADDRESS FAMILY NUMBERS other than to place them into a MIB, which can be found via anonymous FTP at: ftp://ftp.isi.edu/mib/ianaaddressfamilynumbers.mib.6. Security
There are a number of management objects defined in this MIB that have a MAX-ACCESS clause of read-write and/or read-create. Such objects may be considered sensitive or vulnerable in some network environments. The support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations. The NHRP Protocol, RFC 2332 [17], Section 5.2.4.4 discusses security. There is an authentication option which should be utilized to authenticate the source and also provide data integrity to the NHRP payload. This MIB does not contain any managed objects which configure or expose security information such as that needed for NHRP authentication or data integrity. The following items were deemed to jeopardize security and thus, were NOT added to this MIB. Items denoted as (configurable) are those which would need values. Items denoted as (read-only) are those which would provide information. Although the NHRP Protocol [17], requires or has this information, exposing it in a MIB would jeopardize the entire NBMA domain where NHRP was being used. Therefore, these items have been omitted from the MIB.
1. (configurable) enable/disable security
2. (configurable) SPI (security parameter index).
Depending upon the implementation,
there may be multiple SPIs, and these would
be configurable also. For example, if the
implementation switched to a different SPI
after a given time.
3. (configurable) algorithm.
The HMAC-MD5-128 is the default hash algorithm.
4. (configurable) lifetime value in seconds.
5. (read-only) key.
6. (read-only) list of users who have access
to the above information.
7. Intellectual Property
The IETF takes no position regarding the validity or scope of any
intellectual property or other rights that might be claimed to
pertain to the implementation or use of the technology described in
this document or the extent to which any license under such rights
might or might not be available; neither does it represent that it

claims of rights made available for publication and any assurances of
licenses to be made available, or the result of an attempt made to

proprietary rights by implementors or users of this specification can

The IETF invites any interested party to bring to its attention any
copyrights, patents or patent applications, or other proprietary
rights which may cover technology that may be required to practice
