BGP LU (labeled unicast) provides for MPLS transport across IGP boundaries.  By advertising loopbacks and label bindings across IGP boundaries we can communicate to other routers in remote areas that do not share in our local IGP.  BGP LU advertisements only impact edge routers and border routers and not the transport routers in the middle of the connectivity chain.
