The control protocol used for constructing Point-to-Multipoint and
Multipoint-to-Multipoint Label Switched Paths ("MP LSPs") contains a
field that identifies the address of a "root node".  Intermediate
nodes are expected to be able to look up that address in their
routing tables.  However, this is not possible if the route to the root 
node is a BGP route and the intermediate nodes are part of a BGP-free 
core.  This document specifies procedures that enable an
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.  [STANDARDS-TRACK]

This document is a product of the Multiprotocol Label Switching Working
Group of the IETF.

This is now a Proposed Standard Protocol.

STANDARDS TRACK: This document specifies an Internet standards track
protocol for the Internet community,and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Internet
Official Protocol Standards (STD 1) for the standardization state and
status of this protocol.  Distribution of this memo is unlimited.
