    abstract =  {Multi-Topology (MT) routing is supported in IP networks with the use of MT aware IGPs. In order to provide MT routing within Multiprotocol Label Switching (MPLS) Label Distribution Protocol (LDP) networks new extensions are required. This document describes the LDP protocol extensions required to support MT routing in an MPLS environment.},
