The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Information About PIM MIB Extension 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:
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.
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 Extension for IP Multicast
The following example shows how to configure a device to generate notifications indicating that a PIM interface of the device is 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 device 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
