Cisco Cisco IOS Software Release 12.2(14)S

This document describes the PIM MIB Extension for IP Multicast feature in Cisco IOS Release 
12.2(14)S. It includes the following sections:

Protocol Independent Multicast (PIM) is an IP Multicast routing protocol used for routing multicast data 
packets to multicast groups. RFC 2934 defines the Protocol Independent Multicast for IPv4 MIB, which 
describes managed objects that enable users to remotely monitor and configure PIM using Simple 
Network Management Protocol (SNMP).

The PIM MIB Extension for IP Multicast feature introduces support in Cisco IOS software for the 
CISCO-PIM-MIB, which is an extension of RFC 2934 and an enhancement to the existing Cisco 
implementation of the PIM MIB. This feature introduces the following new classes of PIM notifications:

neighbor-change—This notification results from the following conditions:

When a router’s PIM interface is disabled or enabled (using the ip pim command in interface 
configuration mode)

When a router’s PIM neighbor adjacency expires or is established (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 or bootstrap router (BSR) messages.
