Information About PIM MIB Extension for IP Multicast
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)
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).

Configuration Examples for PIM MIB Extensions
Example Enabling PIM MIB Extensions for IP Multicast
The following example shows how to configure a router to generate notifications indicating that a PIM interface of the router has been enabled. The first line configures PIM traps to be sent as SNMP v2c traps to the host with IP address 10.0.0.1. The second line configures the router to send the neighbor-change class of trap notification to the host.
snmp-server host 10.0.0.1 traps version 2c public pim snmp-server enable traps pim neighbor-change interface ethernet0/0 ip pim sparse-dense-mode
