> Abstract:
> 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.
