1. Introduction
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it describes managed objects for the Next Hop
Resolution Protocol (NHRP) as defined in RFC 2332 [17].
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [21].
2. The SNMP Management Framework
The SNMP Management Framework presently consists of five major
components:
o An overall architecture, described in RFC 2571 [1].
o Mechanisms for describing and naming objects and events for the
purpose of management. The first version of this Structure of
Management Information (SMI) is called SMIv1 and described in
STD 16, RFC 1155 [2], STD 16, RFC 1212 [3] and RFC 1215 [4]. The
second version, called SMIv2, is described in STD 58, RFC 2578
[5], STD 58, RFC 2579 [6] and STD 58, RFC 2580 [7].
o Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and
described in STD 15, RFC 1157 [8]. A second version of the SNMP
message protocol, which is not an Internet standards track
protocol, is called SNMPv2c and described in RFC 1901 [9] and RFC
1906 [10]. The third version of the message protocol is called
SNMPv3 and described in RFC 1906 [10], RFC 2572 [11] and RFC 2574
[12].
Greene, et al. Standards Track [Page 2]
RFC 2677 NHRP MIB August 1999
o Protocol operations for accessing management information. The
first set of protocol operations and associated PDU formats is
described in STD 15, RFC 1157 [8]. A second set of protocol
operations and associated PDU formats is described in RFC 1905
[13].
o A set of fundamental applications described in RFC 2573 [14] and
the view-based access control mechanism described in RFC 2575
[15].
A more detailed introduction to the current SNMP Management Framework
can be found in RFC 2570 [16].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the mechanisms defined in the SMI.
This memo specifies a MIB module that is compliant to the SMIv2. A
MIB conforming to the SMIv1 can be produced through the appropriate
translations. The resulting translated MIB must be semantically
equivalent, except where objects or events are omitted because no
translation is possible (use of Counter64). Some machine readable
information in SMIv2 will be converted into textual descriptions in
SMIv1 during the translation process. However, this loss of machine
readable information is not considered to change the semantics of the
MIB.
3. Structure of the MIB
The NHRP MIB contains three groups: the General Group, the Client
Group, and the Server Group.
3.1. The NHRP General Group
The General Group contains objects that apply to both clients and
servers -- in particular the nhrpNextIndex scalar object, the NHRP
Cache Table and the NHRP Purge Request Table.
The nhrpNextIndex scalar object is used to provide unique indices for
the nhprClientIndex in the nhrpClientTable and the nhrpServerIndex in
the nhrpServerTable. If used consistently, this object may prevent
conflicts when multiple managers attempt to create rows
simultaneously in the same table.
Greene, et al. Standards Track [Page 3]
RFC 2677 NHRP MIB August 1999
3.1.1. The NHRP Cache Table
The NHRP Cache Table represents the internetwork layer address to
NBMA address cache that is maintained by both NHRP clients and NHRP
servers.
The NHRP Cache Table contains an ifIndex as part of the Index Clause.
This ifIndex represents the use of a generic ifIndex, such that the
value of this ifIndex SHOULD reflect a specific NBMA subnetwork
related interface as determined by an implementation. For example,
assuming that the NBMA subnetwork is ATM, then it is up to the
implementors of this MIB to determine their own ATM interface
layering (assuming compliance with the IF-MIB, RFC 2233 [18] and the
ATM-MIB, RFC 2515 [19]). In other words, assuming that the NBMA
subnetwork is ATM, the ifIndex in the NHRP Cache Table would
represent the ifIndex containing or consisting of the VC (or
shortcut) denoted by this Table entry.
The indexing scheme for the NHRP Cache Table is very similar to the
MPC Ingress Cache Table and the MPS Ingress Cache Table in the
Multiprotocol Over ATM (MPOA) MIB [23]. This MIB and the MPOA MIB
were designed to be complementary and non-overlapping. The MPOA MIB
should also support this MIB. The MPOA MIB was designed prior to
this MIB, and was designed by the LANE/MPOA Working Group in the ATM
FORUM. The indexing scheme of the NHRP Cache Table (and the NHRP
Server Cache Table) reflect the indexing scheme of the MPC Ingress
Cache Table and the MPS Ingress Cache Table. Although, other
indexing schemes could have been used for the NHRP Cache Table, a
consistent indexing scheme between these tables was thought to be
more advantageous from an implementation standpoint.
3.1.2. The NHRP Purge Request Table
The NHRP Purge Request Table is a way to track Purge Request
Information.
3.2. The NHRP Client Group
The Client Group contains objects that only apply to NHRP clients
(NHCs).
3.2.1. The NHRP Client Table
The NHRP Client Table contains entries for NHRP Next Hop Clients
(NHCs) associated with this agent. Each row in the table represents
a single NHC. The RequestID used in Registration requests needs to
be saved to non-volatile storage. Depending upon the implementation,
Greene, et al. Standards Track [Page 4]
RFC 2677 NHRP MIB August 1999
this may or may not impact how the StorageType is used. For a
complete description of how the Registration RequestID is used, see
Section 5.2.3 of [17].
3.2.2. The NHRP Client Registration Table
The NHRP Client Registration Table contains information on
registration requests which need to be maintained by the Clients.
Each entry in this table represents a single registration request.
Note: since the NHRP specification does not mandate a refresh
algorithm, this table omits refresh information, however, this table
does contain information for all the registration requests which need
to be maintained by the NHRP Clients.
3.2.3. The NHRP Client NHS Table
The NHRP Client NHS Table contains the NBMA subnetwork addresses of
servers configured for use by the client. By default, the agent will
add an entry to this table which corresponds to the client's default
router.
3.2.4. The NHRP Client Statistics Table
The NHRP Client Statistics Table contains NHRP statistics maintained
by a client. These statistics include counters on requests and
replies, as well as counters for errors which are encountered by the
Clients.
3.3. The NHRP Server Group
The Server Group contains objects that only apply to NHRP servers
(NHSes).
3.3.1. The NHRP Server Table
The NHRP Server Table contains entries for each server associated
with this agent.
3.3.2. The NHRP Server Cache Table
The NHRP Server Cache Table contains additional objects that a server
keeps for each entry in its cache. This table extends the NHRP Cache
Table defined in the General Group.
Greene, et al. Standards Track [Page 5]
RFC 2677 NHRP MIB August 1999
3.3.3. The NHRP Server NHC Table
This table contains information about all the Clients known to the
Servers.
3.3.4. The NHRP Server Statistics Table
The NHRP Server Statistics Table contains NHRP statistics maintained
by a server. These statistics include counters on requests and
replies, as well as counters for errors which are encountered by the
Servers.

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.
Greene, et al. Standards Track [Page 62]
RFC 2677 NHRP MIB August 1999
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.
