   The control protocol used for constructing Point-to-Multipoint and
   Multipoint-to-Multipoint Label Switched Paths (&quot;MP LSPs&quot;) contains a
   field that identifies the address of a &quot;root node&quot;.  Intermediate
   nodes are expected to be able to look up that address in their
   routing tables.  However, if the route to the root node is a BGP
   route, and the intermediate nodes are part of a BGP-free core, this
   is not possible.  This document specifies procedures which enable a
   MP LSP to be constructed through a BGP-free core.  In these
   procedures, the root node address is temporarily replaced by an
   address that is known to the intermediate nodes and is on the path to
   the true root node.
