     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

             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.

     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

     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.

     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

     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.
