Abstract:
   In PIM-SM shared LAN networks, there is often more than one upstream
   router.  When PIM Sparse Mode (PIM-SM), including PIM Source
   Specific-Specific Multicast (PIM-SSM), is used, this can lead to
   duplicate IP multicast packets being forwarded by these PIM routers.
   PIM Assert messages are used to elect a single forwarder for each IP
   multicast traffic flow between these routers.

   This document defines a mechanism to send and receive information for
   multiple IP multicast flows in a single PackedAssert message.  This
   optimization reduces the total number of PIM packets on the LAN and
   can therefore speed up the election of the single forwarder, reducing
   the number of duplicate IP multicast packets incurred.
