•
A router's PIM neighbor adjacency expires (defined in RFC 2934)
•
rp-mapping-change--This notification results from a change in the rendezvous point (RP) mapping
information due to either Auto-RP messages or bootstrap router (BSR) messages.
•
invalid-pim-message--This notification results from the following conditions:
•
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)
•
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)

Benefits of PIM MIB Extensions
PIM MIB extensions:
•
Allow users to identify changes in the multicast topology of their network by detecting changes in the
RP mapping.
•
Provide traps to monitor the PIM protocol on PIM-enabled interfaces.
•
Help users identify routing issues when multicast neighbor adjacencies expire on a multicast interface.
•
Enable users to monitor RP configuration errors (for example, errors due to flapping in dynamic RP
allocation protocols like Auto-RP).

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