5.  IANA Considerations

   The ipMRouteRtProto, ipMRouteNextHopProtocol,
   ipMRouteInterfaceProtocol, and ipMRouteProtocol use textual
   conventions imported from the IANA-RTPROTO-MIB.  The purpose of
   defining these textual conventions in a separate MIB module is to
   allow additional values to be defined without having to issue a new
   version of this document.  The Internet Assigned Numbers Authority
   (IANA) is responsible for the assignment of all Internet numbers,
   including various SNMP-related numbers; it will administer the values
   associated with these textual conventions.

   The rules for additions or changes to the IANA-RTPROTO-MIB are
   outlined in the DESCRIPTION clause associated with its MODULE-
   IDENTITY statement.

   The current versions of the IANA-RTPROTO-MIB can be accessed from the
   IANA home page at: "http://www.iana.org/".

6.  Security Considerations

   This MIB contains readable objects whose values provide information
   related to multicast routing, including information on what machines
   are sending to which groups.  There are also a number of objects that
   have a MAX-ACCESS clause of read-write and/or read-create, such as
   those which allow an administrator to configure multicast boundaries.

   While unauthorized access to the readable objects is relatively
   innocuous, unauthorized access to the write-able objects could cause
   a denial of service, or could cause wider distribution of packets
   intended only for local distribution.  Hence, the support for SET
   operations in a non-secure environment without proper protection can
   have a negative effect on network operations.

   SNMPv1 by itself is such an insecure environment.  Even if the
   network itself is secure (for example by using IPSec), even then,
   there is no control as to who on the secure network is allowed to
   access and SET (change/create/delete) the objects in this MIB.

RFC 2932               IPv4 Multicast Routing MIB           October 2000


   It is recommended that the implementers consider the security
   features as provided by the SNMPv3 framework.  Specifically, the use
   of the User-based Security Model RFC 2574 [12] and the View-based
   Access Control Model RFC 2575 [15] is recommended.

   It is then a customer/user responsibility to ensure that the SNMP
   entity giving access to this MIB, is properly configured to give
   access to those objects only to those principals (users) that have
   legitimate rights to access them.

7.  Intellectual Property Notice

   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 implementers 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.
