INTERNET-DRAFT                  NHRP MIB                        May 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 [1].

   This memo specifies a MIB module in a manner that is both compliant
   to the SNMPv2 SMI, and semantically identical to the peer SNMPv1
   definitions.

   This memo does not specify a standard for the Internet community.


1.  The SNMP Network Management Framework

   The SNMP Network Management Framework presently consists of three
   major components.  They are:

   o    the SMI, described in RFC 1902 [2] - the mechanisms used for
        describing and naming objects for the purpose of management.

   o    the MIB-II, STD 17, RFC 1213 [3] - the core set of managed
        objects for the Internet suite of protocols.

   o    the protocol, RFC 1157 [4] and/or RFC 1905 [5], - the protocol
        for accessing managed objects.

   The Framework permits new objects to be defined for the purpose of
   experimentation and evaluation.



1.1.  Object Definitions

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  Objects in the MIB are
   defined using the subset of Abstract Syntax Notation One (ASN.1)
   defined in the SMI.  In particular, each object type is named by an
   OBJECT IDENTIFIER, an administratively assigned name.  The object
   type together with an object instance serves to uniquely identify a
   specific instantiation of the object.  For human convenience, we
   often use a textual string, termed the descriptor, to also refer to
   the object type.

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 NHRP Next Hop Resolution Cache Table and
   the NHRP Purge Request 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 and
   the ATM-MIB).  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.

   As with the IPOA MIB (rfc2320), the use of an NHRP Virtual Interface
   layer is NOT explicitely REQUIRED by the NHRP-MIB.  The Internet
   Assigned Numbers Authority (IANA) ifType nhrp(xxx) was created for
   use by systems that require a virtual NHRP interface layer.  The IF-
   MIB's ifStackTable SHOULD be used to show the relationship between
   vitual NHRP interfaces and the actual subnetwork interface layers.
   The current set of ifType values can be accessed via the IANA
   homepage at: "http://www.iana.org/iana".


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 each client associated
   with this agent. Some agents will allow entries to be created and
   deleted from this table which starts and stops the client entity on
   the station.


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. Some agents will allow entries to be created and
   deleted from this table which starts and stops the server entity on
   the station.


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.


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.

6.  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 vunerable.  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.
