INTERNET-DRAFT NHRP MIB November 1998
Abstract This memo defines an experimental 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. 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. This memo does not specify a standard for the Internet
community.
1. The SNMP Management Framework The SNMP Management
Framework presently consists of five major components:
o An overall architecture, described in RFC 2271 [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 RFC 1155 [2],
RFC 1212 [3] and RFC 1215 [4]. The second version,
called SMIv2, is described in RFC 1902 [5], RFC 1903
[6] and RFC 1904 [7].
o Message protocols for transferring management
information. The first version of the SNMP message
protocol is called SNMPv1 and described in 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
2272 [11] and RFC 2274 [12].
o Protocol operations for accessing management
information. The first set of protocol operations and
associated PDU formats is described in 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
2273 [14] and the view-based access control mechanism
described in RFC 2275 [15]. Managed objects are
accessed via a virtual information store, termed the
Expires May 1999 [Page 2]
INTERNET-DRAFT NHRP MIB November 1998
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.

INTERNET-DRAFT NHRP MIB November 1998
2. Structure of the MIB The NHRP MIB contains three groups:
the General Group, the Client Group, and the Server Group.
2.1. The NHRP General Group The General Group contains
objects that apply to both clients and servers -- in
particular the nhrpNextIndex scalar object, the NHRP Next Hop
Resolution 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, this object
should reduce or eliminate multiple managers creating rows
simultaneously in the same table.
2.1.1. The NHRP Next Hop Resolution Cache Table The NHRP
Next Hop Resolution Cache Table represents the internetwork
layer address to NBMA address cache that is maintained by both
NHRP clients and NHRP servers. The NHRP Next Hop Resolution
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 (either RFC 1573 or RFC 2233) and
the ATM-MIB (RFC 1695)). In other words, still 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.
2.1.2. The NHRP Purge Request Table The NHRP Purge Request
Table is a way to track Purge Request Information.
2.2. The NHRP Client Group The Client Group contains
objects that only apply to NHRP clients (NHCs).
2.2.1. 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
Expires May 1999 [Page 4]
INTERNET-DRAFT NHRP MIB November 1998
non-volatile storage. Depending upon the implementation, 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 [16].
2.2.2. 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.
2.2.3. 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.
2.2.4. 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.
2.3. The NHRP Server Group The Server Group contains
objects that only apply to NHRP servers (NHSes).
2.3.1. The NHRP Server Table The NHRP Server Table contains
entries for each server associated with this agent.
2.3.2. The NHRP Server Next Hop Resolution Cache Table The
NHRP Server Next Hop Resolution Cache Table contains
additional objects that a server keeps for each entry in its
cache. This table extends the NHRP Next Hop Resolution Cache
Table defined in the General Group.
Expires May 1999 [Page 5]
INTERNET-DRAFT NHRP MIB November 1998
2.3.3. The NHRP Server NHC Table This table contains
information about all the Clients known to the Servers.
2.3.4. 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.

4. 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 request made here is for
the IANA to place 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. An example of what
the MIB would look like is included in this document. Please
be aware that the MIB enumerates the ADDRESS FAMILY NUMBERS
values starting with 0 (zero). This was done to preserve the
current values given to the ADDRESS FAMILY VALUES, however, at
some point in the SNMP community enumerations began with 1
(one) and not 0 (zero). 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, of which an example is given in this document (see
IANA Address Family Numbers MIB).

7. Security Considerations Managed Objects which would
configure/expose the security portion of the NHRP protocol [1]
could result in the NHRP protocol being unsecure and
vulnerable. In other words, since there is very minimal
security provided with SNMPv1, and SNMPv3 is at proposed
Standard and is not in wide-spread usage, this MIB document
does not contain objects which would jeopardize the security
of NHRP. Having such objects configurable/visable through SNMP
would defeat the purpose of NHRP's security mechanisms. The
following items/objects may be considered when implementing
the security aspects of NHRP. Items denoted as (configurable)
are those which would need values. Items denoted as (read-
only) are those which may provide relevant information or may
be useful in debugging.
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.
