pimInvalidJoinPruneMsgsRcvd
Module: PIM-STD-MIB
OID (symbolic): PIM-STD-MIB::pimInvalidJoinPruneMsgsRcvd
OID (numeric): 1.3.6.1.2.1.157.1.38
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description:
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.
What is pimInvalidJoinPruneMsgsRcvd?
This OID counts how many malformed or incompatible multicast routing control messages (Join/Prune) a device has received. A message is invalid if it references a group-to-source mapping that conflicts with local configuration. Network operators check this to detect misconfigured multicast routers or topology inconsistencies.
