Status of this Memo

This document is an Internet Draft.  Internet Drafts are working
documents of the Internet Engineering Task Force (IETF), its Areas, and
its Working Groups.  Note that other groups may also distribute working

1.  Introduction

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 used for
managing the Protocol Independent Multicast (PIM) protocol [5,6,7,8].
This MIB module is applicable to IP multicast routers which implement
PIM.



















Draft                           PIM MIB                        June 1996


2.  Revision History

A record of changes which will be removed before publication.

9 June:

(1)  added pimRPSetTable and pimCandidateRPTable.

(2)  deprecated pimRPTable (to retain support for PIM version 1).

(3)  removed pimGroupTable.

(4)  added pimBSRAddress, pimBSRExpiryTime, pimCandidateBSRPreference
     and pimCandidateRPHoldTime.

4 November:

(1)  changed the PIM Group table to hold information common to all RPs
     of a group.

(2)  added the PIM RP table with each entry specific to an RP of a
     group.

(3)  added pimNeighborMode

(4)  modified the pimGroupTable to be indexed by pimGroupAddress and
     pimGroupRP, in order to allow for multiple RPs per group.

15 July - initial version.


3.  The SNMP Network Management Framework

The SNMP Network Management Framework presently consists of three major
components.  They are:

o    RFC 1902 [1] which defines the SMI, the mechanisms used for
     describing and naming objects for the purpose of management.

o    STD 17, RFC 1213 [2] defines MIB-II, the core set of managed
     objects for the Internet suite of protocols.

o    RFC 1157 [3] and RFC 1905 [4] which define two versions of the
     protocol used for network access to managed objects.

Draft                           PIM MIB                        June 1996


The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.


3.1.  Object Definitions

Managed objects are accessed via a virtual information store, termed the
Management Information Base or MIB.  Objects in the MIB are defined
using the subset of Abstract Syntax Notation One (ASN.1) defined in the
SMI.  In particular, each object type is named by an OBJECT IDENTIFIER,
an administratively assigned name.  The object type together with an
object instance serves to uniquely identify a specific instantiation of
the object.  For human convenience, we often use a textual string,
termed the descriptor, to refer to the object type.


4.  Overview

This MIB module contains five scalars and five tables.  The tables are:

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

(2)  the PIM Neighbor Table which contains one row for each of the
     router's PIM neighbors; and

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

(4)  the PIM Candidate-RP Table which 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.

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