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 [I-D.ietf-pim- sm-v2-new] and BIDIR-PIM [I-D.ietf-pim-bidir]). 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. o This MIB module is independent of IP version, whereas RFC 2934 only supported IPv4. o This MIB module includes support for managing BIDIR-PIM. o This MIB module does not include support for managing PIM-DM. o This MIB module does not include support for managing PIM-SM v1. o This MIB module does not depend on the IPv4 Multicast Routing MIB defined in RFC 2932 [RFC2932]. o This MIB module includes support for configuring static RPs. o This MIB module includes support for configuring anycast RPs [I-D.ietf-pim-anycast-rp]>. 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]. 2. 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 Sivaramu, et al. Expires April 7, 2006 [Page 3] Internet-Draft PIM MIB October 2005 [RFC2580]. 3. 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 Sivaramu, et al. Expires April 7, 2006 [Page 4] Internet-Draft PIM MIB October 2005 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. 4.

Expires April 7, 2006 [Page 52] Internet-Draft PIM MIB October 2005 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, the behavior is undefined. 3. If there is at least one such row, from the selected subset of rows, the subset that have the lowest value of pimGroupMappingPrecedence are selected. 4.

If there are 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."

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 or disrupts services provided by the network, including (but not limited to) multicast data traffic delivery. The following tables and objects may also be used to modify multicast routing behavior in order to intercept or subvert any 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. pimKeepalivePeriod pimRegisterSuppressionTime pimInterfaceTable pimInterfaceEntry pimInterfaceHelloInterval pimInterfaceTrigHelloInterval pimInterfaceJoinPruneInterval pimInterfaceDFElectionRobustness pimInterfacePropagationDelay pimInterfaceOverrideInterval pimInterfaceDomainBorder pimInterfaceStatus pimInterfaceStubInterface pimStaticRPTable pimStaticRPEntry pimStaticRPAddressType pimStaticRPGrpAddress pimStaticRPGrpPrefixLength pimStaticRPRPAddress pimStaticRPPimMode pimStaticRPOverrideDynamic pimStaticRPRowStatus pimStaticRPPrecedence Sivaramu, et al.

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. pimKeepalivePeriod pimRegisterSuppressionTime pimStarGEntries pimStarGIEntries pimSGEntries pimSGIEntries pimSGRptEntries pimSGRptIEntries pimInterfaceTable pimInterfaceEntry pimInterfaceIfIndex pimInterfaceIPVersion pimInterfaceAddressType pimInterfaceAddress pimInterfaceDR pimInterfaceHelloInterval pimInterfaceTrigHelloInterval pimInterfaceJoinPruneInterval Sivaramu, et al.

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.
