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.

Top      Up      ToC       Page 63 
     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
   has made any effort to identify any such rights.  Information on the
   IETF's procedures with respect to rights in standards-track and
   standards-related documentation can be found in BCP-11.  Copies of
   claims of rights made available for publication and any assurances of
   licenses to be made available, or the result of an attempt made to
   obtain a general license or permission for the use of such
   proprietary rights by implementors or users of this specification can
   be obtained from the IETF Secretariat.

   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
   this standard.  Please address the information to the IETF Executive
   Director.
