Abstract

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) protocols: PIM-SM (Sparse Mode), BIDIR-PIM (Bidirectional), and PIM-DM (Dense Mode). This document is part of work in progress to obsolete RFC 2934, and is to be preferred where the two documents overlap. This document does not obsolete RFC 2934.

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) protocols (PIM-SM [RFC4601], BIDIR-PIM [RFC5015], and PIM-DM [RFC3973]).

This document is part of work in progress to obsolete RFC 2934 [RFC2934]. RFC 2934 defined an experimental MIB module for managing the PIM protocols. The MIB module defined by this document is a re- working of the MIB module from RFC 2934, with major changes that include the following.

• This MIB module is independent of IP version, whereas RFC 2934 only supported IPv4.

• This MIB module includes support for managing BIDIR-PIM.

• This MIB module retains limited support for managing PIM-DM [RFC3973], but that is no longer its primary purpose.

• This MIB module does not include support for managing PIM-SM v1.

• This MIB module does not depend on the IPv4 Multicast Routing MIB defined in RFC 2932 [RFC2932].

• This MIB module includes support for configuring static Rendezvous Points (RPs).

• This MIB module includes support for configuring anycast RPs [RFC4610].

2. 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 [RFC2119].

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 [RFC3410].

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 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580].

4. Overview

This MIB module contains the following tables.

   1.   The PIM Interface Table, which contains one row per IP version
        for each interface of the router which is running PIM.
   
   2.   The PIM Neighbor Table, which contains one row for each of the
        router's PIM neighbors.
   
   3.   The PIM Neighbor Secondary Address Table, which contains one row
        for each secondary address advertised by each of the router's
        PIM neighbors.
   
   4.   The PIM (*,G) State Table, which contains one row for each group
        for which PIM has (*,G) state.
   
   5.   The PIM (*,G,I) State Table, which contains one row for each
        group and interface for which PIM has interface-specific (*,G)
        state.
   
   6.   The PIM (S,G) State Table, which contains one row for each
        source and group for which PIM has (S,G) state.
   
   7.   The PIM (S,G,I) State Table, which contains one row for each
        source, group, and interface for which PIM has interface-
        specific (S,G) state.
   
   8.   The PIM (S,G,rpt) State Table, which contains one row for each
        source and group for which PIM has (S,G,rpt) state.
   
   9.   The PIM (S,G,rpt,I) State Table, which contains one row for each
        source, group, and interface for which PIM has interface-
        specific (S,G,rpt) state.

10. The PIM Bidir DF-Election Table, which contains one row per interface for each Rendezvous Point (RP) for which Bidirectional-PIM Designated Forwarder (DF) election state is maintained.

11. The PIM Static RP Table, which contains one row per range of multicast group addresses for which a particular configured RP should be used.

12. The PIM Group Mapping Table, which contains one row for each mapping from a multicast group address prefix to the PIM mode and RP address to use for groups within that group prefix, regardless of the source of the group mapping information.

13. The PIM Anycast-RP Set Table, which contains one row for each RP within each Anycast-RP set of which the local router is a member.

   This MIB module uses textual conventions defined in the IF-MIB
   [RFC2863], the INET-ADDRESS-MIB [RFC4001], and the IANA-RTPROTO-MIB
   [RTPROTO].  This MIB module REFERENCEs [RFC3376], [RFC3569],
   [RFC3618], [RFC3810], [RFC3956], [RFC3973], [RFC4601], [RFC4610],
   [RFC5015], [RFC5059], and [IPMCAST-MIB].

A PIM Join/Prune message is invalid if either

• the Group to RP mapping specified by this message does not match the Group to RP mapping on this device, or

• this device believes the group address to be within an SSM address range, but this Join/Prune (*,G) or (S,G,rpt) implies ASM usage.

These conditions can occur transiently while RP mapping changes propagate through the network. If this counter is incremented repeatedly over several minutes, then there is a persisting configuration error that requires correction.

The active Group to RP mapping on this device is specified by the object pimGroupMappingPimMode. If there is no such mapping, then the object pimGroupMappingPimMode is absent. The RP address contained in the invalid Join/Prune is pimInvalidJoinPruneRp.

Invalid Join/Prune messages are discarded. This may result in loss of multicast data affecting listeners downstream of pimInvalidJoinPruneOrigin, for multicast data addressed to pimInvalidJoinPruneGroup.

            Discontinuities in the value of this counter can occur at

            group prefixes to the PIM mode and RP address to use for
            groups within that group prefix.

Rows in this table are created for a variety of reasons, indicated by the value of the pimGroupMappingOrigin object.

• Rows with a pimGroupMappingOrigin value of 'fixed' are created automatically by the router at startup, to correspond to the well-defined prefixes of link-local and unroutable group addresses. These rows are never destroyed.

• Rows with a pimGroupMappingOrigin value of 'embedded' are created by the router to correspond to group prefixes that are to be treated as being in Embedded-RP format.

• Rows with a pimGroupMappingOrigin value of 'configRp' are created and destroyed as a result of rows in the pimStaticRPTable being created and destroyed.

• Rows with a pimGroupMappingOrigin value of 'configSsm' are created and destroyed as a result of configuration of SSM address ranges to the local router.

• Rows with a pimGroupMappingOrigin value of 'bsr' are created as a result of running the PIM Bootstrap Router (BSR) mechanism. If the local router is not the elected BSR, these rows are created to correspond to group prefixes in the PIM Bootstrap messages received from the elected BSR. If the local router is the elected BSR, these rows are created to correspond to group prefixes in the PIM Bootstrap messages that the local router sends. In either case, these rows are destroyed when the group prefixes are timed out by the BSR mechanism.

• Rows with a pimGroupMappingOrigin value of 'other' are created and destroyed according to some other mechanism not specified here.

Given the collection of rows in this table at any point in time, the PIM mode and RP address to use for a particular group is determined using the following algorithm.

1. From the set of all rows, the subset whose group prefix contains the group in question are selected.

2. If there are no such rows, then the group mapping is undefined.

3. If there are multiple selected rows, and a subset is defined by pimStaticRPTable (pimGroupMappingOrigin value of 'configRp') with pimStaticRPOverrideDynamic set to TRUE, then this subset is selected.

4. From the selected subset of rows, the subset that have the greatest value of pimGroupMappingGrpPrefixLength are selected.

5. If there are still multiple selected rows, the subset that has the highest precedence (the lowest numerical value for pimGroupMappingPrecedence) is selected.

6. If there are still multiple selected rows, the row selected is implementation dependent; the implementation might or might not apply the PIM hash function to select the row.

            7. The group mode to use is given by the value of
               pimGroupMappingPimMode from the single selected row; the
               RP to use is given by the value of
               pimGroupMappingRPAddress, unless pimGroupMappingOrigin is
               'embedded', in which case, the RP is extracted from the
               group address in question."

6. Security Considerations

There are a number of management objects defined in this MIB module with a MAX-ACCESS clause of read-write and/or read-create. 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. These are the tables and objects and their sensitivity/vulnerability:

The following tables and objects could be employed to modify multicast routing behavior in a way that prevents, disrupts, or subverts services provided by the network, including (but not limited to) multicast data traffic delivery. 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.

Some of the readable objects in this MIB module (i.e., objects with a MAX-ACCESS other than not-accessible) 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. These are the tables and objects and their sensitivity/vulnerability:

The following tables and objects could be employed to determine 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.

The following tables and objects may also be used to determine whether multicast data is flowing in the network, or has flowed recently. They may also be used to determine the network location 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.

There is also a specific danger arising from the notification pimInvalidRegister. This is originated by devices that receive an incorrect unicast-encapsulated multicast data packet, which poses a clear danger of propagating a DoS (Denial of Service) attack from the data or control plane to the network management plane. The following steps are taken to guard against this.

1. The notification is disabled by default. The writeable field pimInvalidRegisterNotificationPeriod must be set in order to enable it.

2. The syntax of pimInvalidRegisterNotificationPeriod prevents any given device from originating the notification more frequently than once every 10 seconds.

3. The counter pimInvalidRegisterMsgsRcvd provides equivalent function to the notification. Management applications are encouraged to monitor this counter in preference to enabling the notification.

The same measures are taken in respect of pimInvalidJoinPrune, though as this notification can only arise as a result of unroutable control packets, the risk is not so acute.

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 [RFC3410], 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 indeed GET or SET (change/create/delete) them.

7. IANA Considerations

PIM-STD-MIB is rooted under the mib-2 subtree. IANA has assigned { mib-2 157 } to the PIM-STD-MIB module specified in this document.

8. Acknowledgements

This MIB module is based on the original work in RFC 2934 [RFC2934] by K. McCloghrie, D. Farinacci, D. Thaler, and W. Fenner and has been updated based on feedback from the IETF's Protocol Independent Multicast (PIM) Working Group.

Jonathan Nicholas was the editor of early versions of this document, and contributed the objects for management of PIM-DM.
