There are specific requirements for the support of networks 
comprising Label Switching Routers (LSR) participating in different data plane switching layers controlled by a single Generalized Multi 
Protocol Label Switching (GMPLS) control plane instance, referred to 
as GMPLS Multi-Layer Networks/Multi-Region Networks (MLN/MRN).  
        
This document defines extensions to GMPLS routing and signaling 
protocols so as to support the operation of GMPLS Multi-Layer/Multi-
Region Networks. It covers the elements of a single GMPLS control 
plane instance controlling multiple LSP regions or layers within a 
single TE domain.
