2. Abstract

   This document describes a management information base for the IS-IS
   Routing protocol, as described in ISO 10589 [2], when it is used to
   construct routing tables for IP networks, as described in RFC 1195
   [RFC1195].

   This memo defines an experimental portion of the Management
   Information Base (MIB) for use with network management protocols in
   the Internet community.

   This memo is based on an IETF draft by Chris Gunner [1].  This
   version has been modified to include MIB-II syntax, to exclude
   portions of the protocol that are not relevant to IP, such as the
   ES-IS protocol, and to add management support for current practice.

4. Overview

   This document is provided to the IETF working group on IS-IS.

   The IS-IS MIB includes of the following objects

  - isisSystem

       This table contains information specific to a single instance of
       the IS-IS protocol running on a router.

  - isisManAreaAddr

       This table includes area addresses manually configured which are
       used to control the associations formed between Level 1

Internet Draft - draft-ietf-isis-wg-mib-07.txt              January 2002


       Intermediate Systems.

  - isisAreaAddr

       This table includes area addresses reported in relevant L1 LSPs.

  - isisSysProtSupp

       This table includes the manually configured list of protocols,
       such as IP or CLNS, supported by the Intermediate System.

  - isisSummAddr

       This table holds summary addresses configured for each Level 2
       instance of the IS-IS protocol running on a router.

  - isisCirc

       This table contains information specific to a broadcast or
       point-to-point interface in the system.

  - isisCircLevel

       This table contains information specific to a one Level 1 or
       Level 2 of an interface.

  - isisPacketCount

       This optional table contains information on the number of PDUs of
       each type sent at a single level in a single direction.

  - isisISAdj

       This table contains information about adjacencies to routers
       maintained by the protocol.  Entries in this table cannot be
       created by management action: they are established through the
       Hello protocol.

  - isisISAdjAreaAddr

       This table contains the set of Area Addresses of neighboring
       Intermediate Systems as reported in IIH PDUs.

  - isisISAdjIPAddr

       This table contains the set of IP Addresses of neighboring
       Intermediate Systems as reported in received IIH PDUs.

Internet Draft - draft-ietf-isis-wg-mib-07.txt              January 2002


  - isisISAdjProtSupp

       This table contains the set of protocols supported by neighboring
       Intermediate Systems as reported in received IIH PDUs.

  - isisRA

       The Reachable Address Table.

       This table contains information about an address prefix manually
       configured on the system or learned through another protocol.

  - isisIPRA

       The IP Reachable Address Table.

       This table contains information about IP reachable address
       manually configured on this system or learned from another
       protocol.


   The SNMP Management Framework presently consists of five major
   components:

   An overall architecture, described in RFC 2571 [RFC2571].

   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 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC 1215
   [RFC1215].  The second version, called SMIv2, is described in STD 58,
   RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
   [RFC2580].

   Message protocols for transferring management information.  The first
   version of the SNMP message protocol is called SNMPv1 and described
   in STD 15, RFC 1157 [RFC1157].  A second version of the SNMP message
   protocol, which is not an Internet standards track protocol, is
   called SNMPv2c and described in RFC 1901 [RFC1901] and RFC 1906
   [RFC1906].  The third version of the message protocol is called
   SNMPv3 and described in RFC 1906 [RFC1906], RFC 2572 [RFC2572] and
   RFC 2574 [RFC2574].

   Protocol operations for accessing management information.  The first
   set of protocol operations and associated PDU formats is described in
   STD 15, RFC 1157 [RFC1157].  A second set of protocol operations and
   associated PDU formats is described in RFC 1905 [RFC1905].

Internet Draft - draft-ietf-isis-wg-mib-07.txt              January 2002


   A set of fundamental applications described in RFC 2573 [RFC2573] and
   the view-based access control mechanism described in RFC 2575
   [RFC2575].

   A more detailed introduction to the current SNMP Management Framework
   can be found in RFC 2570 [RFC2570].

   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.

         This may be because the system does not generate
         the field, or because there are no common elements.
         The list of protocols supported should be included
         in the notification: it may be empty if the TLV
         is not supported, or if the TLV is empty.

         This should be an edge-triggered notification.

6. Acknowledgments


   This draft MIB is based on a March 1994 Internet Draft by Chris
   Gunnerr, who should be held blameless for the errors introduced since
   then.

   We would like to thank the following individuals for constructive and
   valuable comments:  Neal Castagnoli, Ken Chapman, Satish Dattatri,

7. Security Considerations


   Certain management information defined in this MIB may be considered
   sensitive in some network environments.

   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.

   Therefore, authentication of received SNMP requests and controlled



Jeff Parker - Expires July 2002                                [Page 75]


Internet Draft - draft-ietf-isis-wg-mib-07.txt              January 2002


   access to management information should be employed in such
   environments.

   SNMPv1 by itself is not a secure environment.  Even if the network
   itself is secure (for example by using IPSec), even then, there is no
   control as to who on the secure network is allowed to access and
   GET/SET (read/change/create/delete) the objects in this MIB.

   It is recommended that the implementers consider the security
   features as provided by the SNMPv3 framework.  Specifically, the use
   of the User-based Security Model RFC 2574 [RFC2574] and the View-
   based Access Control Model RFC 2575 [RFC2575] is recommended.

   It is then a customer/user responsibility to ensure that the SNMP
   entity giving access to an instance of this MIB, is properly
   configured to give access to the objects only to those principals
   (users) that have legitimate rights to indeed GET or SET
   (change/create/delete) them.
