Draft IPv4 Multicast Routing MIB July 2000
1. Abstract
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 for IPv4, independent of the specific
multicast routing protocol in use.
2. Introduction
This MIB describes objects used for managing IP Multicast Routing [16],
independent of the specific multicast routing protocol [17-21] in use.
Managed objects specific to particular multicast routing protocols are
specified elsewhere. Similarly, this MIB does not support management of
multicast routing for other address families, including IPv6. Such
management may be supported by other MIBs.
3. The SNMP Management Framework
The SNMP Management Framework presently consists of five major
components:
o An overall architecture, described in RFC 2571 [1].
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 2578 [5], RFC 2579 [6] and RFC 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 2572 [11] and RFC 2574 [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].
Expires January 2000 [Page 2]
Draft IPv4 Multicast Routing MIB July 2000
o A set of fundamental applications described in RFC 2573 [14] and
the view-based access control mechanism described in RFC 2575 [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.
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.
(4) the IP Multicast Scope Boundary Table containing the boundaries
configured for multicast scopes [22].
(5) the IP Multicast Scope Name Table containing human-readable names
of multicast scope.

DESCRIPTION
"An RFC 1766-style language tag, with all alphabetic
characters converted to lowercase. This restriction is
intended to make the lexical ordering imposed by SNMP useful
when applied to language tags. Note that it is
theoretically possible for a valid language tag to exceed
the allowed length of this syntax, and thus be impossible to
represent with this syntax. Sampling of language tags in
current use on the Internet suggests that this limit does
not pose a serious problem in practice."

6. IANA Considerations
The ipMRouteRtProto, ipMRouteNextHopProtocol, ipMRouteInterfaceProtocol,
and ipMRouteProtocol use textual conventions imported from the IANA-
RTPROTO-MIB. The purpose of defining these textual conventions in a
separate MIB module is to allow additional values to be defined without
having to issue a new version of this document. The Internet Assigned
Numbers Authority (IANA) is responsible for the assignment of all
Internet numbers, including various SNMP-related numbers; it will
administer the values associated with these textual conventions.
The rules for additions or changes to the IANA-RTPROTO-MIB are outlined
in the DESCRIPTION clause associated with its MODULE-IDENTITY statement.
The current versions of the IANA-RTPROTO-MIB can be accessed from the
IANA home page at: "http://www.iana.org/".
7. 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 2574 [12] and the View-based Access Control
Model RFC 2575 [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
Expires January 2000 [Page 26]
Draft IPv4 Multicast Routing MIB July 2000
those objects only to those principals (users) that have legitimate
rights to access them.
