RFC 5132 IP MCAST MIB December 2007
1. Introduction
This MIB describes objects used for managing IP multicast function,
including IP multicast routing. These objects are independent of the
specific multicast routing protocol in use. Managed objects specific
to particular multicast protocols are defined elsewhere.
1.1. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC 2119].
2. History
This document obsoletes [RFC 2932]. The MIB module defined by this
document is a re-working of the MIB module from [RFC 2932], with
changes that include the following:
o This MIB module includes support for IPv6 addressing and the IPv6
scoped address architecture. [RFC 2932] supported only IPv4.
o This MIB module allows several multicast protocols to perform
routing on a single interface, where [RFC 2932] assumed each
interface supported at most one multicast routing protocol.
Multicast routing protocols are now per-route, see
ipMcastRouteProtocol.
o This MIB module includes objects that are not specific to
multicast routing. It allows management of multicast function on
systems that do not perform routing, whereas [RFC 2932] was
restricted to multicast routing.
o This MIB module includes a table of Source-Specific Multicast
(SSM) address ranges to which SSM semantics [RFC 3569] should be
applied.
o This MIB module includes a table of local applications that are
receiving multicast data.
o This MIB module includes a table of multicast scope zones.
3. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
[RFC 3410].
McWalter, et al. Standards Track PAGE 2
RFC 5132 IP MCAST MIB December 2007
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
([RFC 2578], [RFC 2579] and [RFC 2580]).
4. Overview
This MIB module contains two scalars and eight tables. The tables
are:
1. The IP Multicast Interface Table, which contains multicast
information specific to interfaces.
2. The IP Multicast SSM Range Table, which contains one row per
range of multicast group addresses to which Source-Specific
Multicast semantics [RFC 3569] should be applied.
3. The IP Multicast Route Table, which contains multicast routing
information for IP datagrams sent by particular sources to the IP
multicast groups known to a system.
4. The IP Multicast Routing Next Hop Table, which contains
information about next-hops for the routing of 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.
5. The IP Multicast Scope Boundary Table, which contains the
boundaries configured for multicast scopes [RFC 2365].
6. The IP Multicast Scope Name Table, which contains human-readable
names for multicast scopes.
7. The IP Multicast Local Listener Table, which contains identifiers
for local applications that are receiving multicast data.
8. The IP Multicast Zone Table, which contains an entry for each
scope zone known to a system, and maps each zone to the multicast
address range that is the corresponding scope.
This MIB module uses textual conventions defined in the IF-MIB
[RFC 2863], the INET-ADDRESS-MIB [RFC 4001] and the IANA-RTPROTO-MIB.
McWalter, et al. Standards Track PAGE 3
RFC 5132 IP MCAST MIB December 2007
5. IMPORTed MIB Modules and REFERENCE Clauses
The MIB modules defined in this document IMPORTs definitions
normatively from the following MIB modules, beyond [RFC 2578],
[RFC 2579], and [RFC 2580]: HCNUM-TC [RFC 2856], IF-MIB [RFC 2863], IANA-
RTPROTO-MIB, SNMP-FRAMEWORK-MIB [RFC 3411], INET-ADDRESS-MIB
[RFC 4001], and LANGTAG-TC-MIB [RFC 5131].
This MIB module also includes REFERENCE clauses that make normative
references to Administratively Scoped IP Multicast [RFC 2365],
Unicast-Prefix-based IPv6 Multicast Addresses [RFC 3306], IPv6 Scoped
Address Architecture [RFC 4007], and IPv6 Addressing Architecture
[RFC 4291].
Finally, this MIB module makes informative references to several RFCs
in the text of DESCRIPTION clauses, including sysApplMIB [RFC 2287],
IP-MIB [RFC 4293], Source-Specific Multicast [RFC 3569], Protocol
Independent Multicast-Sparse Mode version 2 (PIM-SMv2) Protocol
Specification [RFC 4601], Bidirectional Protocol Independent Multicast
(BIDIR-PIM) [RFC 5015], and Tags for Identifying Languages [RFC 4646].

bits are set to zero. This is especially important for this
index field, which is part of the index of this entry. Any
non-zero bits would signify an entirely different entry.
For IPv6 SSM address ranges, only ranges prefixed by
FF3x::/16 are permitted, where 'x' is a valid IPv6 RFC 4291
multicast address scope. The syntax of the address range is
given by RFC 3306, Sections 4 and 7.
For addresses of type ipv4z or ipv6z, the appended zone
index is significant even though it lies beyond the prefix
length. The use of these address types indicate that this
SSM range entry applies only within the given zone. Zone
index zero is not valid in this table.
If non-global scope SSM range entries are present, then
consistent ipMcastBoundaryTable entries are required on
routers at the zone boundary."

When no name is specified, the default value of this object
for IPv4 should be the string 239.x.x.x/y with x and y
replaced with decimal values to describe the address and
mask length associated with the scope.
When no name is specified, the default value of this object
for IPv6 should be the string FF0x::/16, with x replaced by
the hexadecimal value for the RFC 4291 multicast scope.
An IPv6 address prefixed by FF1x::/16 is a non-permanently-
assigned address. An IPv6 address prefixed by FF3x::/16 is
a unicast-prefix-based multicast addresses. A scope
FF0x::/16 implies an identical scope name for these other

7. Security Considerations
7.1. SNMPv3
SNMP versions prior to SNMPv3 did not include adequate security.
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 GET/SET (read/change/create/delete) the objects
in this MIB module.
It is RECOMMENDED that implementers consider the security features as
provided by the SNMPv3 framework (see [RFC 3410], section 8),
including full support for the SNMPv3 cryptographic mechanisms (for
authentication and privacy).
Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to
enable cryptographic security. It is then a customer/operator
responsibility to ensure that the SNMP entity giving access to an
instance of this MIB module is properly configured to give access to
the objects only to those principals (users) that have legitimate
rights to access (read/change/create/delete) them.
7.2. Writeable Objects
There are a number of management objects defined in this MIB module
with a MAX-ACCESS clause of read-write and/or read-create. This
section discusses and lists these elements.
Such objects may be considered sensitive or vulnerable in some
network environments. The support for SET operations in a non-secure
environment without proper protection can have a negative effect on
network operations.
In this MIB module, possible effects that can be induced by SET
operations on writeable objects include:
o Modifications to multicast routing behavior that prevent or
disrupt services provided by the network, including (but not
limited to) multicast data traffic delivery.
o Modifications to multicast routing behavior that allow
interception or subversion of information that is carried by the
network. For example, attacks can be envisaged that would pass
nominated multicast data streams through a nominated location,
without the sources or listeners becoming aware of this
subversion.
McWalter, et al. Standards Track PAGE 54
RFC 5132 IP MCAST MIB December 2007
The following are the read-write and read-create objects defined in
this MIB module.
ipMcastEnabled ipMcastDeviceConfigStorageType ipMcastInterfaceTtl
ipMcastInterfaceRateLimit ipMcastInterfaceStorageType
ipMcastSsmRangeRowStatus ipMcastSsmRangeStorageType
ipMcastBoundaryStatus ipMcastBoundaryStorageType
ipMcastScopeNameString ipMcastScopeNameDefault ipMcastScopeNameStatus
ipMcastScopeNameStorageType
7.3. Readable Objects
As well as the writeable objects discussed above, there are a number
of readable objects (i.e., objects with a MAX-ACCESS other than not-
accessible) that may be considered sensitive or vulnerable in some
network environments. It is thus important to control even GET
and/or NOTIFY access to these objects and possibly to even encrypt
the values of these objects when sending them over the network via
SNMP.
In this MIB module, possible effects that can be induced by GET
and/or NOTIFY operations include:
o Determination of the topology, disposition, and composition of the
network. This information may be commercially sensitive, and may
also be used in preparation for attacks, including any of the
attacks described above.
o Determinion of whether multicast data is flowing in the network,
or has flowed recently, as well as the locations of senders and
recipients. An attacker can apply 'traffic analysis' to this
data. In some cases, the information revealed by traffic analyses
can be as damaging as full knowledge of the data being
transported.
8. IANA Considerations
IPMCAST-MIB is rooted under the mib-2 subtree. IANA has assigned {
mib-2 168 } to the IPMCAST-MIB module specified in this document.
9. Acknowledgements
This MIB module is based on the original work in [RFC 2932] by K.
McCloghrie, D. Farinacci, and D. Thaler.
Suggested IPv6 multicast MIBs by R. Sivaramu and R. Raghunarayan have
been used for comparison while editing this MIB module.
