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 and IPv6,
independent of the specific multicast routing protocol in use.
2. Introduction
This MIB describes objects used for managing IPv4 and IPv6
Multicast Routing[2],independent of the specific multicast routing
protocol [3,4,5,6,7] in use. This MIB extends the MIB proposed in
[8]. 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.
Such management may be supported by other MIBs.
3. The SNMP Management Framework
1
draft-thaler-idmr-multicast-routemib-1 June 2000
The SNMP Management Framework presently consists of five major
components:
o An overall architecture, described in RFC 2571 [9].
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 [10], RFC 1212 [11] and RFC 1215 [12]. The second version,
called SMIv2, is described in RFC 2578 [13], RFC 2579 [14] and RFC
2580 [15].
o Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and
described in RFC 1157 [16]. A second version of the SNMP message
protocol, which is not an Internet standards track protocol, is
called SNMPv2c and described in RFC 1901 [17] and RFC 1906 [18].
The third version of the message protocol is called SNMPv3 and
described in RFC 1906 [18], RFC 2572 [19] and RFC 2574 [20].
o Protocol operations for accessing management information. The
first set of protocol operations and associated PDU formats is
described in RFC 1157 [16]. A second set of protocol operations and
associated PDU formats is described in RFC 1905 [21].
o A set of fundamental applications described in RFC 2573 [22]
and the view-based access control mechanism described in RFC 2575
[23].
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:
Thaler,Adams,Siadak Experimental/Expires Dec 2000 2
draft-thaler-idmr-multicast-routemib-1 June 2000
(1) the Multicast Route Table containing multicast routing
information for datagrams sent by particular sources to the
multicast groups known to a router.
(2) the Multicast Routing Next Hop Table containing information
on the next-hops for the routing multicast datagrams. Each entry
is one of a list of next-hops on outgoing interfaces for particular
qsources sending to a particular multicast group address.
(3) the Multicast Routing Interface Table containing multicast
routing information specific to interfaces.
(4) the Multicast Scope Boundary Table containing the boundaries
configured for multicast scopes [24].
(5) the 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 [20] and the View-
based Access Control Model RFC 2575 [23] 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.
