Abstract

This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. Specifically, this document describes a MIB for the Intermediate System to Intermediate System (IS-IS) Routing protocol when it is used to construct routing tables for IP networks.

1. The Internet-Standard Management Framework

For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to section 7 of RFC 3410 [RFC3410]. Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. MIB objects are generally accessed through the Simple Network Management Protocol (SNMP). Objects in the MIB are defined using the mechanisms defined in the Structure of Management Information (SMI). This memo specifies a MIB module that is compliant to the SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580].

2. Overview

This document describes a management information base for the Intermediate System to Intermediate System (IS-IS) Routing protocol, as described in ISO 10589 [ISO10589], when it is used to construct routing tables for IP networks, as described in RFC 1195 [RFC1195]. The objects are mainly derived from the Guidelines for Definition of Managed Objects (GDMO) definitions in ISO 10589 and from the GDMO definitions in ISO 10733 [ISO10733]. There are also additional objects for managing the IP-specific functionality of Integrated IS- IS operation. This MIB imports definitions from SNMPv2-TC [RFC2579], SNMPv2-SMI [RFC2578], SNMPv2-CONF [RFC2580], SNMP-FRAMEWORK-MIB [RFC3411], DIFFSERV-MIB [RFC3289], IF-MIB [RFC2863], and INET-ADDRESS-MIB [RFC4001]. See the imports section of the MIB for the specific items imported. This MIB defines some objects to manage Mesh Groups, described in [RFC2973], and a three-way handshake for point-to-point adjacencies, described in [RFC3373]. The IS-IS MIB defines the following objects: System-Wide Attributes - isisSystem This table contains information specific to a single instance of the IS-IS protocol running on a router.
Top   ToC   RFC4444 - Page 3
      -  isisManAreaAddr

         This table includes area addresses that are manually
         configured, which are used to control the associations formed
         between Level 1 Intermediate Systems.

      -  isisAreaAddr

         This table includes area addresses reported in relevant L1
         LSPs.

      -  isisSummAddr

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

      -  isisRedistributeAddr

         This table provides criteria to decide whether a route should
         be leaked from L2 to L1 when Domain Wide Prefix leaking is
         enabled.

      -  isisRouter

         This table holds the hostname and router ID for Intermediate
         Systems in the network.

      -  isisSysLevel

         This table contains information specific to a domain (Level 2)
         or an area (Level 1) of the IS-IS protocol.

      -  isisNextCircIndex

         This scalar is used to provide a unique circuit index.

   Circuit-specific Attributes

      -  isisCirc

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

      -  isisCircLevel

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

   Counters

      -  isisSystemCounter

         Counters in the System table, such as number of times we have
         wrapped a sequence counter on one of our Link State PDUs.

      -  isisCircuitCounter

         Counters of events particular to a circuit, such as PDUs with
         an illegal value of the System ID field length.

      -  isisPacketCounter

         Counts of IS-IS Protocol PDUs broken down into packet type.

   Attributes associated with an Adjacency

      -  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.

      -  isisISAdjProtSupp

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

   Attributes Associated with Addresses

      -  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 an IP reachable address
         manually configured on this system or learned from another
         protocol.

   Attributes Associated with Link State PDU Table

      -  isisLSPSummaryTable

         The Link State PDU Summary Table.

         This table contains information contained in the headers of
         Link State PDUs stored by the system.

      -  isisLSPTLVTable

         The Link State PDU TLV Table.

         This table holds the sequence of TLVs that make up an LSP
         fragment.

   Attributes Associated with a Notification

      -  isisNotification

         This table defines attributes that will be included when
         reporting IS-IS notifications.
