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 presently consists of three
major components. They are:
o the SMI, described in RFC 1902 [1] - the mechanisms used for
describing and naming objects for the purpose of management.
o the MIB-II, STD 17, RFC 1213 [2] - the core set of managed
objects for the Internet suite of protocols.
o the protocol, STD 15, RFC 1157 [3] and/or RFC 1905 [4], -
the protocol for accessing 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
3.1. Structure of MIB
Managing DVMRP routers requires the following groups of information:
o General statistics.
o DVMRP configuration information common to all multicast-capable
interfaces.
o Information to store DVMRP neighbor information.
o Information to store the DVMRP routing table.
3.1.1. General Description
Expires October 1997 [Page 2]
Draft DVMRP MIB April 1997
This MIB controls all aspects of the DVMRP protocol. It consists of
four groups:
o The dvmrpGeneralGroup is used to describe general configuration
information.
o The dvmrpInterfaceGroup is used to describe interface
configuration and statistics, and augments the Multicast Routing
Interface Table from the IP Multicast MIB [7].
o The dvmrpNeighborGroup is used to describe peer configuration
and statistics.
o The dvmrpRoutingGroup is used to store the DVMRP routing table.
3.2. Relationship to the Interfaces MIB
This section clarifies the relationship of this MIB to the Interfaces
MIB [8]. Several areas of correlation are addressed in the following
subsections. The implementor is referred to the Interfaces MIB docu-
ment in order to understand the general intent of these areas.
3.2.1. Layering Model
A DVMRP interface may consist of either a virtual encapsulation
interface (tunnel) or a physical interface. Each physical interface
has an ifEntry in the Interfaces MIB [8]. Tunnels are handled by
creating a logical interface (ifEntry) for each tunnel. These are
then correlated to physical interfaces using the ifStack table of the
Interfaces MIB.
Typically, DVMRP tunnels use IP-in-IP encapsulation [9], although
other encapsulation methods may be used as well. The basic model,
therefore, looks something like this (for example):
| | | | | |
+--+ +---+ +--+ +---+ | |
|IP-in-IP| | GRE | | |
| tunnel | | tunnel | | |
+--+ +---+ +--+ +---+ | |
| | | | | | <== attachment to physical
+--+ +---------+ +----------+ +--+ interfaces, to be provided
| Physical interface | by ifStack table
+--------------------------------+
3.2.2. ifTestTable
The ifTestTable usage is defined in the MIBs defining the
Expires October 1997 [Page 3]
Draft DVMRP MIB April 1997
encapsulation below the network layer. For example, if IP-in-IP
encapsulation is being used, the ifTestTable is defined by IP-in-IP.
3.2.3. ifRcvAddressTable
The ifRcvAddressTable usage is defined in the MIBs defining the
encapsulation below the network layer. For example, if IP-in-IP
encapsulation is being used, the ifRcvAddressTable is defined by IP-
in-IP.
3.2.4. ifEntry
IfEntries are defined in the MIBs defining the encapsulation below
the network layer. For example, if IP-in-IP encapsulation [9] is
being used, the ifEntry is defined by IP-in-IP.
ifEntries will never be created by the DVMRP MIB. The DVMRP MIB
always depends on some other ifIndex of some set of ifTypes. That
is, to create an entry in the DVMRP MIB, the base ifEntry must
already have been created through some other mechanism.
The DVMRP interface entry does have its own RowStatus, permitting the
DVMRP supplementary information to come and go, but not otherwise
disturbing the ifIndex to which it is attached. If in a given imple-
mentation the two are tightly bound, deleting the ifEntry may have
the side effect of deleting the DVMRP interface entry.
3.3. Relationship to other MIBs
3.3.1. Relationship to the IP Multicast MIB
Implementation of the IP Multicast MIB [7] is required.
3.3.2. Relationship to the IP Tunnel MIB
Implementation of the IP Tunnel MIB [10] is required to support
management of IP-in-IP tunnels which are commonly used with DVMRP.
4. Revision History
A record of changes which will be removed before publication.
17 April 1997
(1) renamed dvmrpVersion to dvmrpVersionString and
dvmrpVInterfaceTable to dvmrpInterfaceTable (with
appropriate name changes to all member objects)
Expires October 1997 [Page 4]
Draft DVMRP MIB April 1997
for clarity.
(2) deprecated most of the objects in the dvmrpVInterfaceTable,
and all of the dvmrpAltNetTable, since they duplicate objects
now present in other MIBs.
(3) added dvmrpInterfaceRcvBadPkts, dvmrpInterfaceRcvBadRoutes,
dvmrpNeighborRcvRoutes, dvmrpNeighborRcvBadPkts, and
dvmrpNeighborRcvBadRoutes.
(4) added dvmrpRouteUpTime.
13 June 1996
(1) moved dvmrpBoundaryTable to the IP Multicast MIB.
(2) replaced dvmrpNeighborVersion with dvmrpNeighborMajorVersion,
dvmrpNeighborMinorVersion, and dvmrpNeighborCapabilities.
11 December 1995
(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 1995
(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 1995 - initial version.
