	Title		: In-band signaling for Point-to-Multipoint and Multipoint-to-Multipoint Label Switched Paths

When an IP multicast tree needs to pass through an MPLS domain, it is
   advantageous to map the tree to a Point-to-Multipoint or Multipoint-
   to-Multipoint Label Switched Path.  This document specifies a way to provide a one-one mapping between IP multicast trees and Label
   Switched Paths.  The IP multicast control messages are translated
   into MPLS control messages when they enter the MPLS domain, and are
   translated back into IP multicast control messages at the far end of
   the MPLS domain.  The IP multicast control information is coded into
   the MPLS control information in such a way as to ensure that a single
   Multipoint Label Switched Path gets set up for each IP multicast
   tree.
