  15. 1.) Status of this memo
  16.  
  17.    This memo proposes an extension to the SNMP MIB to support the
  18.    adaptation of the ISO  Inter-Domain Routing Protocol ([1]) for that
  19.    enables it to be used as an Inter-Autonomous System routing protocol
  20.    in the TCP/IP Internet. This adaptation will be  called "IDRP for IP"
  21.    [2] in this  document.
  22.  
  23.    Dual IDRP is defined to be a single instance of IDRP that can
  24.    simultaneously support Inter-Domain/Inter-Autonomous System routing
  25.    in the TCP/IP and OSI Internets.   An OSI IDRP for the
  26.     purposes of this paper is defined to be an implementation of the ISO
  27.    Inter-Domain Routing Protocol as defined in [1].
  28.  
  29.    The whole family of IDRP related documents and their functoins are
  30.    listed in [3].
  31.  
  32.    This memo has two main parts and one appendix:         - IDRP General
  33.    MIB , and         - IDRP for IP  MIB         - appendix A -
  34.                    IDRP for IP MIB in GDMO

  51.    deciding on what managed objects should go into the IDRP GDMO.  From
  52.    the IDRP GDMO, the same managed objects plus additions have been

  90.  
  91.  
  92. Managed objects are accessed via a virtual information store, termed the
  93. Management Information Base or MIB.  Objects in the MIB are defined
  94. using the subset of Abstract Syntax Notation One (ASN.1) [10] defined in
  95. the SMI.  In particular, each object has a name, a syntax, and an
  96. encoding.  The name is an object identifier, an administratively
  97. assigned name, which specifies an object type.  The object type together
  98. with an object instance serves to uniquely identify a specific
  99. instantiation of the object.  For human convenience, we often use a
  100. textual string, termed the OBJECT DESCRIPTOR, to also refer to the
  101. object type.
  102.  
  103. The syntax of an object type defines the abstract data structure
  104. corresponding to that object type.  The ASN.1 language is used for this
  105. purpose.  However, the SMI [5] purposely restricts the ASN.1 constructs
  106. which may be used.  These restrictions are explicitly made for
  107. simplicity.
  108.  
  109. The encoding of an object type is simply how that object type is
  110. represented using the object type's syntax.  Implicitly tied to the
  111. notion of an object type's syntax and encoding is how the object type is
  112. represented when being transmitted on the network.
  113.  
  114. The SMI specifies the use of the basic encoding rules of ASN.1 [11],
  115. subject to the additional requirements imposed by the SNMP.

  139. 4.) Overview
  140.  
  141.    These objects are used to control and manage a IDRP for IP [x]
  142.    implementation.
  143.  
  144.  
  145.    IDRP  ([1])  is   defined  as  the   protocol  for  exchange   of
  146.    Inter-Domain  routing  information  between routers  to  support
  147.    forwarding  of  ISO  8473 (Connectionless   Network  Layer Protocol
  148.    (CLNP))[4] PDUs.   The "IDRP for IP"  document [2] contains the a
  149.    description adaptation of the IDRP protocol definition that enables
  150.    it to be used as protocol for the exchange of inter-autonomous system
  151.    information among routers to support the forwarding of IP packets
  152.    across multiple autonomous systems.
  153.  
  154.    The adaptation is defined  is such a way that a Dual IDRP will be
  155.    able to fully interoperate with IDRP for IP.
  156.  
  157.    This document contains two main parts, and two informative
  158.    appendices:
  159.         -IDRP General MIB (section 5) -IDRP for IP MIB (section 6)
  160.         -Appendix A -         IDRP for IP MIB in GDMO -Appendix B -
  161.                 ISO IDRP GMDO for CLNP (8473) only         (What to not
  162.         implement for IDRP for          IP)
  163.  
  164.         The IDRP General MIB specifies the managed objects which are
  165.         protocol specific, and may be used in either an IDRP for IP,
  166.         OSI IDRP,  or Dual IDRP.  The IDRP for IP MIB section lists
  167.         managed objects needed for the IDRP for IP MIB.
  168.  
  169.         Appendix A - "IDRP for IP MIB in GDMO" recast the IDRP for IP
  170.         MIB in ISO GDMO language.  This appendix will allow implementors
  171.         of the IDRP GDMO to quickly add in the IDRP for IP MIB.
  172.  
  173.         Appendix B - ISO IDRP GDMO for CLNP only will list the GDMO
  174.         contained in the ISO IDRP document which does not need to be
  175.         implemented for the IDRP for IP implementations.  Again, this
  176.         appendix will allow implementors of the IDRP GDMO to quickly
  177.         delete all CLNP references from the general IDRP
  178.         implementations.
  179.  
  180.         The GMDO definitions in Appendix A and Appendix B are listed in
  181.         with GDMO variable and reference to the IDRP document.  These
  182.         definitions are tied to a specific version of the ISO IDRP
  183.         standard [1].  The version will be noted in each appendix.   As
  184.         new version of the IDRP standard is released, these GDMO
  185.         definitions may change.   The reader should refer to the ISO
  186.         standard for the authortative GDMO definitions.

  205. 5.1 IDRP for IP General MIB comments
  206.  
  207.    The IDRP for IP General MIB contains four sets of general IDRP
  208.    variables from the ISO IDRP protocol:
  209.  
  210.       1.) idrpConfig package 2.) adjacentBis package 3.) Actions 4.)
  211.       Traps which Notify about IDRP problem
  212.    The idrpConfig package is a group of attributes which are needed to
  213.    configure a IDRP for IP BIS. One example of such BIS configuration
  214.    variable is idrpVersion  which indicates the version of the IDRP that
  215.    this BIS defaults to using.
  216.  
  217.    --EDITOR's note: IDRP Configuration information can take two tacts:
  218.    -- for IDRP for IP only.  The IDRP for IP only can simply leave the
  219.    -- CLNPAddress as null or not there.  Or an IDRP for IP MIB can --
  220.    simply delete these Variables and have different tables.  I -- have
  221.    taken the first approach since it seems the overhead is -- just a
  222.    little for the Dual MIB, and will be more cohesive in -- the end.  An
  223.    IDRP for IP MIB parsers could simply -- ignore any request for CLNP
  224.    variable, or could simply enter -- a MIB with a null value.  The
  225.    total extra overhead for CLNP -- on top of the IDRP for IP package
  226.    seems very little --
  227.  
  228.    The adjacentBis package is a group of attributes which configure or
  229.    record statistics for a connection with an adjacent BIS.  A similar
  230.    group of variables in  the BGP-3 mib is the bgpPeerTable.
  231.  
  232.    The actions in the ISO protocols must be translated to attributes for
  233.    SNMP's support.  The two IDRP actions - start a BIS-BIS connection
  234.    and stop a BIS-BIS connection are encoded in one action variable.
  235.  
  236.    The TRAP section encodes the ISO IDRP protocol's notifications into
  237.    SNMP traps.  The variables included in the Notifications are
  238.    dependent on whether the protocol is running IDRP for IP only, OSI
  239.    IDRP or Dual IDRP.
  240.  
  241.    IDRP for IP MIB assumes that:
  242.     - the IpAddress from RFC-1213 will exist in any router using IDRP
  243.     for IP;
  244.  
  245.     - clnpAddress from RFC-1238 will be in any router using OSI IDRP;
  246.     and
  247.  
  248.     - IpAddress from RFC-1213  and clnpAddress from the RFC-1213 will be
  249.     exist in any router router doing Dual-IDRP.
  250.  
  251. 5.1.1) IdrpConfig Package Variables n
  252.    configured for this IDRP router (Border Intermediate System (BIS)).
  253.    The idrpConfig package does not has only two counterparts in the
  254.    BGP-3 MIB: bgpVersion and bgpLocalAS.  The equivalent IDRP for IP MIB
  255.    variables are:

  515.              BGP-3 specifies only IP.  This IDRP for IP General MIB
  516.              specifies both IP Address and OSI address.  For an
  517.              IP only implementation, The BisNET variable is NULL.

  533.  
  534.  
  535.         *2 - The ISO IDRP specification specifies two actions instead
  536.              of the variable.   The ability to specify actions is not
  537.              available in SNMP.
  538.  
  539.         *3 - The BisPeerLocalAddr identifies a local IP address which
  540.              identifies a local port  to use to send the BGP packets
  541.              to reach this remote peer.  However, the ISO concept
  542.              uses a local SNPA address.  While this MIB variable
  543.              is not in the ISO specification, suggestions will
  544.              be made to include it in the ISO DIS ballot.
  545.  
  546.         *4 - BGP-3/4 uses a TCP connection, while IDRP uses a
  547.              reliable transport inside the protocol.  Thus these
  548.              variables are not necessary.
  549.  
  550.         *5 - bgpRemoteAS may relate to the bisRDI and BisRdc.
  551.              Please see the IDRP for IP document for the use of

  560.    Historically, the ISO IDRP actions came from bgp-3 MIB variable
  561.    bgpPeerAdminStatus.  The two ISO IDRP actions startEvent and
  562.    stopEvent are encoded in the IDRP for IP MIB variable

  2411.    OSI IDRP, these definitions have been placed in the common MIB
  2412.    portion.   An implementation of IDRP for IP, should leave the
