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
documents as Internet Drafts.
Internet Drafts are valid for a maximum of six months and may be
updated, replaced, or obsoleted by other documents at any time. It is
inappropriate to use Internet Drafts as reference material or to cite
them other than as a "work in progress".
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]. This
MIB module is applicable to IP multicast routers which implement PIM.
Draft PIM MIB February 1995
2. The SNMPv2 Network Management Framework
The SNMPv2 Network Management Framework consists of four major
components. They are:
o RFC 1442 [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 1445 [3] which defines the administrative and other
architectural aspects of the framework.
o RFC 1448 [4] which defines the protocol used for network access to
managed objects.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
2.1. 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.
3. Overview
This MIB module contains one scalar and three 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 Group Table which contains the PIM information for IP
multicast groups which is common to all Rendezvous Points (RPs) of
Expires August 1995 [Page 2]
Draft PIM MIB February 1995
a group.
(4) the PIM RP Table which contains the PIM information for IP
multicast groups which is speciifc to a particular RP.
4. Revision History
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.
