Abstract

When PIM Sparse Mode (PIM-SM), including PIM Source-SpecificMulticast (PIM-SSM), is used in shared LAN networks, there is oftenmore than one upstream router. This can lead to duplicate IPmulticast packets being forwarded by these PIM routers. PIM Assertmessages are used to elect a single forwarder for each IP multicasttraffic flow between these routers.

This document defines a mechanism to send and receive information formultiple IP multicast flows in a single PackedAssert message. Thisoptimization reduces the total number of PIM packets on the LAN andcan therefore speed up the election of the single forwarder, reducingthe number of duplicate IP multicast packets incurred.
