This document describes the unnecessary multicast stream flooding
problem in the link layer switches between multicast source and PIM
First Hop Router (FHR). The IGMP-Snooping Switch will forward
multicast streams to router ports, and the PIM FHR must receive all
multicast streams even if there is no request from receiver. This
often leads to waste of switchs' cache and link bandwidth when the
multicast streams are not actually required. This document details
the problem and defines design goals for a generic mechanism to
restrain the unnecessary multicast stream flooding.
