1. Introduction
This memo defines a 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 Protocol
Independent Multicast (PIM) protocol [18,19].
2. The SNMP Network Management Framework
The SNMP Management Framework presently consists of five major
components:
* An overall architecture, described in RFC 2571 [1].
* 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 STD 16,
RFC 1155 [2], STD 16, RFC 1212 [3] and RFC 1215 [4]. The second
version, called SMIv2, is described in STD 58, RFC 2578 [5], STD 58,
RFC 2579 [6] and STD 58, RFC 2580 [7].
* Message protocols for transferring management information. The first
version of the SNMP message protocol is called SNMPv1 and described
in STD 15, 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].
* Protocol operations for accessing management information. The first
set of protocol operations and associated PDU formats is described in
STD 15, RFC 1157 [8]. A second set of protocol operations and
associated PDU formats is described in RFC 1905 [13].
* 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.
3. Overview
This MIB module contains one scalar and eight tables. Some of the
objects in these tables are deprecated. This MIB contains deprecated
objects since they are necessary for managing PIMv1 routers, but PIMv1
itself is obsoleted by PIM v2 [18,19].
The tables contained in this MIB are:
(1) The PIM Interface Table contains one row for each of the
router's PIM interfaces.
(2) The PIM Neighbor Table contains one row for each of the router's
PIM neighbors.
(3) The PIM IP Multicast Route Table contains one row for each
multicast routing entry whose incoming interface is running PIM.
(4) The PIM Next Hop Table which contains one row for each outgoing
interface list entry in the multicast routing table whose
interface is running PIM, and whose state is pruned.
(5) The (deprecated) PIM RP Table contains the PIM (version 1)
information for IP multicast groups which is common to all RPs
of a group.
(6) The PIM RP-Set Table contains the PIM (version 2) information
for sets of candidate Rendezvous Points (RPs) for IP multicast
group addresses with particular address prefixes.
(7) The PIM Candidate-RP Table contains the IP multicast groups for
which the local router is to advertise itself as a Candidate-RP.
If this table is empty, then the local router advertises itself
as a Candidate-RP for all groups.
(8) The PIM Component Table contains one row for each of the PIM
domains to which the router is connected.

5. Security Considerations
This MIB contains readable objects whose values provide information
related to multicast routing, including information on the network
topology. There are also a number of objects that have a MAX-ACCESS
clause of read-write and/or read-create, which allow an administrator
to configure PIM in the router.
While unauthorized access to the readable objects is relatively
innocuous, unauthorized access to the write-able objects could cause
a denial of service. 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.
