A alaPimNeighborLoss 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 alaPimNeighborLossCount is incremented, subject to the rate limit specified by alaPimNeighborLossNotificationPeriod.

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

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

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

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

An entry (conceptual row) in the alaPimInterfaceTable. 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 alaPimInterfaceAddressType 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 alaPimInterfaceAddressType object.

The Designated Router Priority value inserted into the DR Priority option 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 alaPimInterfaceHelloInterval, or 65535 if alaPimInterfaceHelloInterval 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 alaPimInterfaceJoinPruneInterval, or 65535 if alaPimInterfaceJoinPruneInterval is set to zero. PIM-DM implementations are recommended to use the value of alaPimInterfacePruneLimitInterval.

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 the interface to be deactivated and then reactivated.

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 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 valid values have been written to alaPimStaticRPRPAddress. All writeable 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 alaPimGroupMappingOrigin object. - Rows with a alaPimGroupMappingOrigin 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 alaPimGroupMappingOrigin 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 alaPimGroupMappingOrigin value of 'configRp' are created and destroyed as a result of rows in the alaPimStaticRPTable being created and destroyed. - Rows with a alaPimGroupMappingOrigin value of 'configSsm' are created and destroyed as a result of configuration of SSM address ranges to the local router. - Rows with a alaPimGroupMappingOrigin 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 alaPimGroupMappingOrigin 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. From the selected subset of rows, the subset that have the greatest value of alaPimGroupMappingGrpPrefixLength are selected. 4. If there are multiple selected rows, and a subset are defined by alaPimStaticRPTable (alaPimGroupMappingOrigin value of 'configRp') with alaPimStaticRPOverrideDynanic set to TRUE, then this subset is selected. 5. If there are still multiple selected rows, the subset that have the highest precedence (the lowest numerical value for alaPimGroupMappingPrecedence) are 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 alaPimGroupMappingPimMode from the single selected row; the RP to use is given by the value of alaPimGroupMappingRPAddress, unless alaPimGroupMappingOrigin is 'embedded', in which case the RP is extracted from the group address in question.

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 alaPimDeviceConfigStorageType.

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 alaPimDeviceConfigStorageType.

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 alaPimLastAssertGroupAddressType object.

The address type of the multicast 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 multicast source address in the most recently sent or received assert. The InetAddressType is given by the alaPimLastAssertSourceAddressType object.

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

The number of neighbor loss events that have occurred. This count 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 alaPimNeighborLoss 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 alaPimInvalidRegister notifications originated by this router. The default value of 65535 represents an 'infinite' time, in which case no alaPimInvalidRegister 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 alaPimDeviceConfigStorageType.

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 alaPimGroupMappingPimMode. If there is no such mapping, then the object alaPimGroupMappingPimMode is absent. The RP address contained in the invalid Register is alaPimInvalidRegisterRp. Multicast data carried by invalid Register messages is discarded. The discarded data is from a source directly connected to alaPimInvalidRegisterOrigin, and is addressed to alaPimInvalidRegisterGroup. 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 alaPimInvalidRegisterOrigin, alaPimInvalidRegisterGroup and alaPimInvalidRegisterRp. If no unexpected Register messages have been received, then this object is set to unknown(0).

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

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

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

The minimum time that must elapse between alaPimInvalidJoinPrune notifications originated by this router. The default value of 65535 represents an 'infinite' time, in which case no alaPimInvalidJoinPrune 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 alaPimDeviceConfigStorageType.

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 alaPimGroupMappingPimMode. If there is no such mapping, then the object alaPimGroupMappingPimMode is absent. The RP address contained in the invalid Join/Prune is alaPimInvalidJoinPruneRp. Invalid Join/Prune messages are discarded. This may result in loss of multicast data affecting listeners downstream of alaPimInvalidJoinPruneOrigin, for multicast data addressed to alaPimInvalidJoinPruneGroup. 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 alaPimInvalidJoinPruneOrigin, alaPimInvalidJoinPruneGroup and alaPimInvalidJoinPruneRp. If no unexpected Join/Prune messages have been received, this object is set to unknown(0).

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

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

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

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

The number of changes to active RP mappings on this device. Information about active RP mappings is available in alaPimGroupMappingTable. Only changes to active mappings cause this count to be incremented. That is, changes that modify the alaPimGroupMappingEntry with the highest precedence for a group (lowest value of alaPimGroupMappingPrecedence). 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 alaPimInterfaceElection notifications originated by this router. The default value of 65535 represents an 'infinite' time, in which case no alaPimInterfaceElection notifications are ever sent. The storage type of this object is determined by alaPimDeviceConfigStorageType.

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 alaPimDeviceConfigStorageType.

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: alaPimKeepalivePeriod, alaPimRegisterSuppressionTime, alaPimNeighborLossNotificationPeriod, alaPimInvalidRegisterNotificaationPeriod, alaPimInvalidJoinPruneNotificationPeriod, alaPimRPMappingNotificationPeriod, alaPimInterfaceElectionNotificationPeriod and alaPimRefreshInterval.
