   In PIM-SM networks PIM Register messages are sent by the Designated
   Router (DR) to the Rendezvous Point (RP) to signal the presence of
   Multicast sources in the network.  There are periodic PIM Null-
   Registers sent by a DR to the RP to keep the state alive at the RP as
   long as the source is active.  The PIM Null-Register message carries
   information about a single Multicast source and group.

   This document defines a standard to send information about multiple
   multicast sources and multicast groups in a single PIM Null-Register
   message, in a packed format.  This document also discusses the
   interoperability between PIM routers that support the new packed
   message format and PIM routers that do not support the new format.
