PIM MIB Extensions for SNMP Traps for IP Multicast
Protocol Independent Multicast (PIM) is an IP multicast routing protocol used for routing multicast data packets to multicast groups. RFC 2934 defines the PIM MIB for IPv4, which describes managed objects that enable users to remotely monitor and configure PIM using Simple Network Management Protocol (SNMP).
PIM MIB extensions introduce the following new classes of PIM notifications:
neighbor-change--This notification results from the following conditions:
- A router’s PIM interface is disabled or enabled (using the ip pim command in interface configuration mode)
- 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)
