Cisco Cisco IOS Software Release 12.2(14)S

invalid-pim-message—This notification results from the following conditions:

When an invalid (*, G) join or prune message is received by the device (for example, when a 
router receives a join or prune message for which the RP specified in the packet is not the RP 
for the multicast group)

When an invalid PIM register message is received by the device (for example, when a router 
receives a register message from a multicast group for which it is not the RP)

Allows users to identify changes in the multicast topology of their network by detecting changes in 
the RP mapping.

Provides traps to monitor the PIM protocol on PIM-enabled interfaces.

Helps users identify routing issues when multicast neighbor adjacencies expire or are established on 
a multicast interface.

Enables users to monitor RP configuration errors (for example, errors due to flapping in dynamic 
RP allocation protocols like Auto-RP).

The following MIB tables are not supported in Cisco IOS software:

pimIpMRouteTable

pimIpMRouteNextHopTable

The pimInterfaceVersion object was removed from RFC 2934 and, therefore, is no longer supported in 
Cisco IOS software.
