Title : Using mLDP through a Backbone where there is no Route to the Root

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, 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 which is known to the intermediate nodes.
