1.  Motivation

1.1.  Overview of PIM-SM

   Protocol Independent Multicast - Sparse Mode (PIM-SM) was first
   published as [RFC2117] in 1997.  This version was then obsoleted by
   [RFC2362] in 1998.  The protocol was classified as Experimental in
   both documents.  The protocol specification was then rewritten in
   whole and advanced to Proposed Standard as [RFC4601] in 2006.
   Considering its multiple independent implementations developed and
   sufficient successful operational experience gained, the PIM WG
