The MIB module for management of PIM routers. Copyright (C) The IETF Trust (2007). This version of this MIB module is part of RFC 5060; see the RFC itself for full legal notices.

A pimNeighborLoss notification signifies the loss of an adjacency with a neighbor. This notification should be generated when the neighbor timer expires, and the router has no other neighbors on the same interface with the same IP version and a lower IP address than itself. This notification is generated whenever the counter pimNeighborLossCount is incremented, subject to the rate limit specified by pimNeighborLossNotificationPeriod.

A pimInvalidRegister notification signifies that an invalid PIM Register message was received by this device. This notification is generated whenever the counter pimInvalidRegisterMsgsRcvd is incremented, subject to the rate limit specified by pimInvalidRegisterNotificationPeriod.

A pimInvalidJoinPrune notification signifies that an invalid PIM Join/Prune message was received by this device. This notification is generated whenever the counter pimInvalidJoinPruneMsgsRcvd is incremented, subject to the rate limit specified by pimInvalidJoinPruneNotificationPeriod.

A pimRPMappingChange notification signifies a change to the active RP mapping on this device. This notification is generated whenever the counter pimRPMappingChangeCount is incremented, subject to the rate limit specified by pimRPMappingChangeNotificationPeriod.

A pimInterfaceElection notification signifies that a new DR or DF has been elected on a network. This notification is generated whenever the counter pimInterfaceElectionWinCount is incremented, subject to the rate limit specified by pimInterfaceElectionNotificationPeriod.

The (conceptual) table listing the router's PIM interfaces. PIM is enabled on all interfaces listed in this table.

An entry (conceptual row) in the pimInterfaceTable. This entry is preserved on agent restart.

The ifIndex value of this PIM interface.

The IP version of this PIM interface. A physical interface may be configured in multiple modes concurrently, e.g., IPv4 and IPv6; however, the traffic is considered to be logically separate.

The address type of this PIM interface.

The primary IP address of this router on this PIM interface. The InetAddressType is given by the pimInterfaceAddressType object.

The value of the Generation ID this router inserted in the last PIM Hello message it sent on this interface.

The primary IP address of the Designated Router on this PIM interface. The InetAddressType is given by the pimInterfaceAddressType object.

The Designated Router Priority value inserted into the DR Priority option in PIM Hello messages transmitted on this interface. Numerically higher values for this object indicate higher priorities.

Evaluates to TRUE if all routers on this interface are using the DR Priority option.

The frequency at which PIM Hello messages are transmitted on this interface. This object corresponds to the 'Hello_Period' timer value defined in the PIM-SM specification. A value of zero represents an 'infinite' interval, and indicates that periodic PIM Hello messages should not be sent on this interface.

The maximum time before this router sends a triggered PIM Hello message on this interface. This object corresponds to the 'Trigered_Hello_Delay' timer value defined in the PIM-SM specification. A value of zero has no special meaning and indicates that triggered PIM Hello messages should always be sent immediately.

The value set in the Holdtime field of PIM Hello messages transmitted on this interface. A value of 65535 represents an 'infinite' holdtime. Implementations are recommended to use a holdtime that is 3.5 times the value of pimInterfaceHelloInterval, or 65535 if pimInterfaceHelloInterval is set to zero.

The frequency at which this router sends PIM Join/Prune messages on this PIM interface. This object corresponds to the 't_periodic' timer value defined in the PIM-SM specification. A value of zero represents an 'infinite' interval, and indicates that periodic PIM Join/Prune messages should not be sent on this interface.

The value inserted into the Holdtime field of a PIM Join/Prune message sent on this interface. A value of 65535 represents an 'infinite' holdtime. Implementations are recommended to use a holdtime that is 3.5 times the value of pimInterfaceJoinPruneInterval, or 65535 if pimInterfaceJoinPruneInterval is set to zero. PIM-DM implementations are recommended to use the value of pimInterfacePruneLimitInterval.

The minimum number of PIM DF-Election messages that must be lost in order for DF election on this interface to fail.

Evaluates to TRUE if all routers on this interface are using the LAN Prune Delay option.

The expected propagation delay between PIM routers on this network or link. This router inserts this value into the Propagation_Delay field of the LAN Prune Delay option in the PIM Hello messages sent on this interface. Implementations SHOULD enforce a lower bound on the permitted values for this object to allow for scheduling and processing delays within the local router.

The value this router inserts into the Override_Interval field of the LAN Prune Delay option in the PIM Hello messages it sends on this interface. When overriding a prune, PIM routers pick a random timer duration up to the value of this object. The more PIM routers that are active on a network, the more likely it is that the prune will be overridden after a small proportion of this time has elapsed. The more PIM routers are active on this network, the larger this object should be to obtain an optimal spread of prune override latencies.

Whether or not this interface is a PIM domain border. This includes acting as a border for PIM Bootstrap Router (BSR) messages, if the BSR mechanism is in use.

Whether this interface is a 'stub interface'. If this object is set to TRUE, then no PIM packets are sent out this interface, and any received PIM packets are ignored. Setting this object to TRUE is a security measure for interfaces towards untrusted hosts. This allows an interface to be configured for use with IGMP (Internet Group Management Protocol) or MLD (Multicast Listener Discovery) only, which protects the PIM router from forged PIM messages on the interface. To communicate with other PIM routers using this interface, this object must remain set to FALSE. Changing the value of this object while the interface is operational causes PIM to be disabled and then re-enabled on this interface.

The minimum interval that must transpire between two successive Prunes sent by a router. This object corresponds to the 't_limit' timer value defined in the PIM-DM specification. This object is used only by PIM-DM.

The minimum interval that must transpire between two successive Grafts sent by a router. This object corresponds to the 'Graft_Retry_Period' timer value defined in the PIM-DM specification. This object is used only by PIM-DM.

Evaluates to TRUE if all routers on this interface are using the State Refresh option. This object is used only by PIM-DM.

The value of the Propagation_Delay field of the LAN Prune Delay option received from this neighbor. This object is always zero if pimNeighborLanPruneDelayPresent is FALSE.

The value of the Override_Interval field of the LAN Prune Delay option received from this neighbor. This object is always zero if pimNeighborLanPruneDelayPresent is FALSE.

If pimStaticRPOverrideDynamic is set to TRUE, all dynamic RP configuration is overridden by this static configuration, whatever the value of this object. The absolute values of this object have a significance only on the local router and do not need to be coordinated with other routers. A setting of this object may have different effects when applied to other routers. Do not use this object unless fine control of static RP behavior on the local router is required.

The status of this row, by which rows in this table can be created and destroyed. This status object cannot be set to active(1) before a valid value has been written to pimStaticRPRPAddress. All writable objects in this entry can be modified when the status of this entry is active(1).

The storage type for this row. Rows having the value 'permanent' need not allow write-access to any columnar objects in the row.

This table is used to manage Anycast-RP via PIM Register messages, as opposed to via other protocols such as MSDP (Multicast Source Discovery Protocol). Entries must be configured in this table if and only if the local router is a member of one or more Anycast-RP sets, that is, one or more Anycast-RP addresses are assigned to the local router. Note that if using static RP configuration, this is in addition to, not instead of, the pimStaticRPTable entries that must be configured for the Anycast-RPs. The set of rows with the same values of both pimAnycastRPSetAddressType and pimAnycastRPSetAnycastAddress corresponds to the Anycast-RP set for that Anycast-RP address. When an Anycast-RP set configuration is active, one entry per pimAnycastRPSetAnycastAddress corresponds to the local router. The local router is identified by the pimAnycastRpSetLocalRouter object. That entry determines the source address used by the local router when forwarding PIM Register messages within the Anycast-RP set.

An entry corresponds to a single router within a particular Anycast-RP set. This entry is preserved on agent restart.

The address type of the Anycast-RP address and router address.

The Anycast-RP address. The InetAddressType is given by the pimAnycastRPSetAddressType object.

The address of a router that is a member of the Anycast-RP set. The InetAddressType is given by the pimAnycastRPSetAddressType object. This address differs from pimAnycastRPSetAnycastAddress. Equal values for these two addresses in a single entry are not permitted. That would cause a Register loop.

Whether this entry corresponds to the local router.

The status of this row, by which rows in this table can be created and destroyed. This status object can be set to active(1) without setting any other columnar objects in this entry. All writable objects in this entry can be modified when the status of this entry is active(1).

The storage type for this row. Rows having the value 'permanent' need not allow write-access to any columnar objects in the row.

The (conceptual) table listing mappings from multicast 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.

An entry (conceptual row) in the pimGroupMappingTable.

The mechanism by which this group mapping was learned.

The address type of the IP multicast group prefix.

The IP multicast group address that, when combined with pimGroupMappingGrpPrefixLength, gives the group prefix for this mapping. The InetAddressType is given by the pimGroupMappingAddressType object. This address object is only significant up to pimGroupMappingGrpPrefixLength bits. The remainder of the address bits are 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.

The multicast group prefix length that, when combined with pimGroupMappingGrpAddress, gives the group prefix for this mapping. The InetAddressType is given by the pimGroupMappingAddressType object. If pimGroupMappingAddressType is 'ipv4' or 'ipv4z', this object must be in the range 4..32. If pimGroupMappingAddressType is 'ipv6' or 'ipv6z', this object must be in the range 8..128.

The address type of the RP to be used for groups within this group prefix, or unknown(0) if no RP is to be used or if the RP address is unknown. This object must be unknown(0) if pimGroupMappingPimMode is ssm(2), or if pimGroupMappingOrigin is embedded(6).

The IP address of the RP to be used for groups within this group prefix. The InetAddressType is given by the pimGroupMappingRPAddressType object.

The PIM mode to be used for groups in this group prefix.

The precedence of this row, used in the algorithm that determines which row applies to a given group address (described above). Numerically higher values for this object indicate lower precedences, with the value zero denoting the highest precedence. The absolute values of this object have a significance only on the local router and do not need to be coordinated with other routers.

The duration of the Keepalive Timer. This is the period during which the PIM router will maintain (S,G) state in the absence of explicit (S,G) local membership or (S,G) join messages received to maintain it. This timer period is called the Keepalive_Period in the PIM-SM specification. It is called the SourceLifetime in the PIM-DM specification. The storage type of this object is determined by pimDeviceConfigStorageType.

The duration of the Register Suppression Timer. This is the period during which a PIM Designated Router (DR) stops sending Register-encapsulated data to the Rendezvous Point (RP) after receiving a Register-Stop message. This object is used to run timers both at the DR and at the RP. This timer period is called the Register_Suppression_Time in the PIM-SM specification. The storage type of this object is determined by pimDeviceConfigStorageType.

The number of entries in the pimStarGITable.

The number of entries in the pimSGTable.

The number of entries in the pimSGITable.

The number of entries in the pimSGRptTable.

The number of Asserts sent by this router. Discontinuities in the value of this counter can occur at re-initialization of the management system, for example, when the device is rebooted.

The number of Asserts received by this router. Asserts are multicast to all routers on a network. This counter is incremented by all routers that receive an assert, not only those routers that are contesting the assert. Discontinuities in the value of this counter can occur at re-initialization of the management system, for example, when the device is rebooted.

The interface on which this router most recently sent or received an assert, or zero if this router has not sent or received an assert.

The address type of the multicast group address in the most recently sent or received assert. If this router has not sent or received an assert, then this object is set to unknown(0).

The multicast group address in the most recently sent or received assert. The InetAddressType is given by the pimLastAssertGroupAddressType object.

The address type of the source address in the most recently sent or received assert. If the most recent assert was (*,G), or if this router has not sent or received an assert, then this object is set to unknown(0).

The source address in the most recently sent or received assert. The InetAddressType is given by the pimLastAssertSourceAddressType object.

The minimum time that must elapse between pimNeighborLoss notifications originated by this router. The maximum value 65535 represents an 'infinite' time, in which case, no pimNeighborLoss notifications are ever sent. The storage type of this object is determined by pimDeviceConfigStorageType.

The number of neighbor loss events that have occurred. This counter is incremented when the neighbor timer expires, and the router has no other neighbors on the same interface with the same IP version and a lower IP address than itself. This counter is incremented whenever a pimNeighborLoss notification would be generated. Discontinuities in the value of this counter can occur at re-initialization of the management system, for example, when the device is rebooted.

The minimum time that must elapse between pimInvalidRegister notifications originated by this router. The default value of 65535 represents an 'infinite' time, in which case, no pimInvalidRegister notifications are ever sent. The non-zero minimum allowed value provides resilience against propagation of denial-of-service attacks from the data and control planes to the network management plane. The storage type of this object is determined by pimDeviceConfigStorageType.

The number of invalid PIM Register messages that have been received by this device. A PIM Register message is invalid if either o the destination address of the Register message does not match the Group to RP mapping on this device, or o this device believes the group address to be within an SSM address range, but this Register 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 Register is pimInvalidRegisterRp. Multicast data carried by invalid Register messages is discarded. The discarded data is from a source directly connected to pimInvalidRegisterOrigin, and is addressed to pimInvalidRegisterGroup. Discontinuities in the value of this counter can occur at re-initialization of the management system, for example, when the device is rebooted.

The address type stored in pimInvalidRegisterOrigin, pimInvalidRegisterGroup, and pimInvalidRegisterRp. If no invalid Register messages have been received, then this object is set to unknown(0).

The source address of the last invalid Register message received by this device.

The IP multicast group address to which the last invalid Register message received by this device was addressed.

The RP address to which the last invalid Register message received by this device was delivered.

The minimum time that must elapse between pimInvalidJoinPrune notifications originated by this router. The default value of 65535 represents an 'infinite' time, in which case, no pimInvalidJoinPrune notifications are ever sent. The non-zero minimum allowed value provides resilience against propagation of denial-of-service attacks from the control plane to the network management plane. The storage type of this object is determined by pimDeviceConfigStorageType.

The number of invalid PIM Join/Prune messages that have been received by this device. A PIM Join/Prune message is invalid if either o the Group to RP mapping specified by this message does not match the Group to RP mapping on this device, or o 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 re-initialization of the management system, for example, when the device is rebooted.

The address type stored in pimInvalidJoinPruneOrigin, pimInvalidJoinPruneGroup, and pimInvalidJoinPruneRp. If no invalid Join/Prune messages have been received, this object is set to unknown(0).

The source address of the last invalid Join/Prune message received by this device.

The IP multicast group address carried in the last invalid Join/Prune message received by this device.

The RP address carried in the last invalid Join/Prune message received by this device.

The minimum time that must elapse between pimRPMappingChange notifications originated by this router. The default value of 65535 represents an 'infinite' time, in which case, no pimRPMappingChange notifications are ever sent. The storage type of this object is determined by pimDeviceConfigStorageType.

The number of changes to active RP mappings on this device. Information about active RP mappings is available in pimGroupMappingTable. Only changes to active mappings cause this counter to be incremented. That is, changes that modify the pimGroupMappingEntry with the highest precedence for a group (lowest value of pimGroupMappingPrecedence). Such changes may result from manual configuration of this device, or from automatic RP mapping discovery methods including the PIM Bootstrap Router (BSR) mechanism. Discontinuities in the value of this counter can occur at re-initialization of the management system, for example, when the device is rebooted.

The minimum time that must elapse between pimInterfaceElection notifications originated by this router. The default value of 65535 represents an 'infinite' time, in which case, no pimInterfaceElection notifications are ever sent. The storage type of this object is determined by pimDeviceConfigStorageType.

The number of times this device has been elected DR or DF on any interface. Elections occur frequently on newly-active interfaces, as triggered Hellos establish adjacencies. This counter is not incremented for elections on an interface until the first periodic Hello has been sent. If this router is the DR or DF at the time of sending the first periodic Hello after interface activation, then this counter is incremented (once) at that time. Discontinuities in the value of this counter can occur at re-initialization of the management system, for example, when the device is rebooted.

The interval between successive State Refresh messages sent by an Originator. This timer period is called the RefreshInterval in the PIM-DM specification. This object is used only by PIM-DM. The storage type of this object is determined by pimDeviceConfigStorageType.

The storage type used for the global PIM configuration of this device, comprised of the objects listed below. If this storage type takes the value 'permanent', write-access to the listed objects need not be allowed. The objects described by this storage type are: pimKeepalivePeriod, pimRegisterSuppressionTime, pimNeighborLossNotificationPeriod, pimInvalidRegisterNotificationPeriod, pimInvalidJoinPruneNotificationPeriod, pimRPMappingNotificationPeriod, pimInterfaceElectionNotificationPeriod, and pimRefreshInterval.
