             Distance-Vector Multicast Routing Protocol MIB
                    <draft-thaler-dvmrp-mib-03.txt>


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 draft documents 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

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 Distance-Vector Multicast Routing Protocol (DVMRP) protocol
[5,6].  This MIB module is applicable to IP multicast routers which
implement DVMRP.

2.  The SNMPv2 Network Management Framework

The SNMPv2 Network Management Framework consists of four major com-
ponents.  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 four scalars and five tables.  The tables are:

(1)  the DVMRP Virtual Interface Table which contains one row for each
     of the router's DVMRP virtual interfaces, and augments the
     Multicast Routing Interface Table from the IP Multicast MIB [7];

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

(3)  the DVMRP Route Table which contains one row for each subnet in
     the routing table;

(4)  the DVMRP Routing Next Hop Table containing information on the

     next hops for the routing IP multicast datagrams.  Each entry
     is one of a list of next hops on outgoing virtual interfaces
     for a particular subnet origin;

(5)  the DVMRP Alternate Subnet Table which contains one row for each
     additional subnet on a physical interface.


4.  Revision History

13 June

(1)  moved dvmrpBoundaryTable to the IP Multicast MIB

(2)  replaced dvmrpNeighborVersion with dvmrpNeighborMajorVersion,
     dvmrpNeighborMinorVersion, and dvmrpNeighborCapabilities

11 December

(1)  added dvmrpNumRoutes and dvmrpReachableRoutes gauges to aid
     in detecting specific MBone problems.

(2)  added dvmrpVInterfaceStatus and changed MAX-ACCESS of existing
     columns to allow remote configuration of tunnels.

(3)  added dvmrpAltNetTable to allow management of alternate subnet
     information on physical interfaces.

6 June

(1)  updated dvmrpMIB with IANA-assigned OID

(2)  added dvmrpVInterfaceInOctets and dvmrpVInterfaceOutOctets

(3)  added subnet(4) to dvmrpVInterfaceType

(4)  modified dvmrpNeighborTable to be INDEX-ed by
     dvmrpNeighborVifIndex and dvmrpNeighborAddress

(5)  added dvmrpRouteTable and dvmrpRouteNextHopTable

23 March - initial version.
