RFC 2934      Protocol Independent Multicast MIB for IPv4   October 2000


1.  Introduction

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   In particular, it describes managed objects used for managing the
   Protocol Independent Multicast (PIM) protocol [16,17,18,19].  This
   MIB module is applicable to IPv4 multicast routers which implement
   PIM.  This MIB does not support management of PIM for other address
   families, including IPv6.  Such management may be supported by other
   MIBs.

2.  The SNMP Network 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
        STD 16, RFC 1155 [2], STD 16, RFC 1212 [3] and RFC 1215 [4].
        The second version, called SMIv2, is described in STD 58, RFC
        2578 [5], STD 58, RFC 2579 [6] and STD 58, RFC 2580 [7].

   o    Message protocols for transferring management information.  The
        first version of the SNMP message protocol is called SNMPv1 and
        described in STD 15, 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 2572 [11] and
        RFC 2574 [12].

   o    Protocol operations for accessing management information.  The
        first set of protocol operations and associated PDU formats is
        described in STD 15, 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 2573 [14] and
        the view-based access control mechanism described in RFC 2575
        [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.

RFC 2934      Protocol Independent Multicast MIB for IPv4   October 2000


   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.

3.  Overview

   This MIB module contains one scalar and eight tables.  Some of the
   objects in these tables are deprecated.  This MIB contains deprecated
   objects since they are necessary for managing PIMv1 routers, but
   PIMv1 itself is obsoleted by PIMv2 [18,19].

   The tables contained in this MIB are:


   (1)  The PIM Interface Table contains one row for each of the
        router's PIM interfaces.

   (2)  The PIM Neighbor Table contains one row for each of the router's
        PIM neighbors.

   (3)  The PIM IP Multicast Route Table contains one row for each
        multicast routing entry whose incoming interface is running PIM.

   (4)  The PIM Next Hop Table which contains one row for each outgoing
        interface list entry in the multicast routing table whose
        interface is running PIM, and whose state is pruned.

   (5)  The (deprecated) PIM RP Table contains the PIM (version 1)
        information for IP multicast groups which is common to all RPs
        of a group.

   (6)  The PIM RP-Set Table contains the PIM (version 2) information
        for sets of candidate Rendezvous Points (RPs) for IP multicast
        group addresses with particular address prefixes.

   (7)  The PIM Candidate-RP Table contains the IP multicast groups for
        which the local router is to advertise itself as a Candidate-RP.
        If this table is empty, then the local router advertises itself
        as a Candidate-RP for all groups.

   (8)  The PIM Component Table contains one row for each of the PIM
        domains to which the router is connected.
