Draft                   IP Multicast Routing MIB                May 1999

1.  Introduction  Abstact

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 IP Multicast Routing [16], for IPv4, independent of the specific

Draft
multicast routing protocol in use.

2.  Introduction

This MIB describes objects used for managing IP Multicast Routing MIB               July 1998 [16],
independent of the specific multicast routing protocol [17-21] in use.
Managed objects specific to particular multicast routing protocols are
specified elsewhere.

2.  Revision History

A record  Similarly, this MIB does not support management of changes which will be removed before publication.

23 July 1998

(1)  added ipMRouteRtProto, ipMRouteRtAddr, ipMRouteRtMask, and
     ipMRouteRtType to get the route used by the
multicast forwarding
     entry.  This provides functionality equivalent to mtrace.

(2)  added ipMRouteScopeTable routing for mapping admin boundaries to user-
     friendly scope names.

(3)  changed comments on pimSparseMode and pimDenseMode enumeration
     values to clarify that they other address families, including IPv6.  Such
management may be used for PIMv1.

(4)  added security considerations and copyright notice

20 November 1997

(1)  made ipMRouteInterfaceProtocol read-only.

(2)  added ipMRouteInterfaceRateLimit, ipMRouteInterfaceInMcastOctets,
     ipMRouteInterfaceOutMcastOctets, ipMRouteInterfaceHCInMcastOctets,
     and ipMRouteInterfaceHCOutMcastOctets, with the HC objects in a new
     conformance group.

26 March

(1)  added ipMRouteInterfaceProtocol.

(2)  added protocol values for PIM-DM, PIM-SM, and IGMP-only links.

26 November

(1)  moved ipMRouteNextHopPkts to its own conformance group.

9 June

(1)  added the ipMRouteBoundaryTable and ipMRouteNextHopPkts.

Draft                   IP Multicast Routing MIB               July 1998

(2)  updated references, etc.

28 March

(1)  renamed ipMRouteNextHopClosestMember to
     ipMRouteNextHopClosestMemberHops, and ipMRouteDifferentInIfIndexes
     to ipMRouteDifferentInIfPacket.

26 February

(1)  added ipMRouteNextHopAddress as a INDEX variable for the
     ipMRouteNextHopTable.

(2)  added ipMRouteNextHopClosestMember and ipMRouteNextHopProtocol

(3)  added ipMRouteMIBHopCountGroup.

(4)  specified that an expiry-time of zero means that an entry is not
     subject to aging.

(5)  added references for MOSPF and CBT.

4 February

(1)  removed ipMRouteOutList

(2)  Modified ipMRouteNextHopTable to be INDEX-ed supported by
     ipMRouteNextHopGroup, ipMRouteNextHopSource,
     ipMRouteNextHopSourceMask, and ipMRouteNextHopIfIndex.

(3)  added ipMRouteProtocol

(4)  replaced "RPF" terminology with "Upstream neighbor".

15 July - initial version. other MIBs.

3.  The SNMP Management Framework

The SNMP Management Framework presently consists of five major
components:

o    An overall architecture, described in RFC 2271 [1].

Draft                   IP Multicast Routing MIB               July 1998

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 RFC
     1155 [2], RFC 1212 [3] and RFC 1215 [4]. The second version, called
     SMIv2, is described in RFC 1902 2578 [5], RFC 1903 2579 [6] and RFC 1904 2580 [7].

o    Message protocols for transferring management information. The
     first version of the SNMP message protocol is called SNMPv1 and
     described in 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 2272 [11] and RFC 2274 [12].

o    Protocol operations for accessing management information. The first
     set of protocol operations and associated PDU formats is described
     in RFC 1157 [8]. A second set of protocol operations and associated
     PDU formats is described in RFC 1905 [13].

Draft                   IP Multicast Routing MIB                May 1999

o    A set of fundamental applications described in RFC 2273 [14] and
     the view-based access control mechanism described in RFC 2275 [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.

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.

3.1.  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

Draft                   IP Multicast Routing MIB               July 1998
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 one scalar and five tables.  The tables are:

(1)  the IP Multicast Route Table containing multicast routing
     information for IP datagrams sent by particular sources to the IP
     multicast groups known to a router.

(2)  the IP Multicast 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 interfaces for particular
     sources sending to a particular multicast group address.

(3)  the IP Multicast Routing Interface Table containing multicast
     routing information specific to interfaces.

Draft                   IP Multicast Routing MIB                May 1999

(4)  the IP Multicast Scope Boundary Table containing the boundaries
     configured for multicast scopes [22].

(5)  the IP Multicast Scoped Boundary Scope Name Table containing the boundaries
     configured for human-readable names
     of multicast scopes. scope.

6.  Security Considerations

This MIB contains readable objects whose values provide information
related to multicast routing, including information on what machines are
sending to which groups.  There are also a number of objects that have a
MAX-ACCESS clause of read-write and/or read-create, such as those which
allow an administrator to configure multicast boundaries.

While unauthorized access to the readable objects is relatively
innocuous, unauthorized access to the write-able objects could cause a
denial of service, or could cause wider distribution of packets intended
only for local distribution.  Hence, the support for SET operations in a
non-secure environment without proper protection can have a negative
effect on network operations.

SNMPv1 by itself is such an insecure environment.  Even if the network
itself is secure (for example by using IPSec), even then, there is no
control as to who on the secure network is allowed to access and SET
(change/create/delete) the objects in this MIB.

It is recommended that the implementers consider the security features
as provided by the SNMPv3 framework.  Specifically, the use of the
User-based Security Model RFC 2274 [12] and the View-based Access
Control Model RFC 2275 [15] is recommended.

It is then a customer/user responsibility to ensure that the SNMP entity
giving access to this MIB, is properly configured to give access to
those objects only to those principals (users) that have legitimate
rights to access them.
