Abstract

Multi-Topology (MT) routing is supported in IP networks with the use of MT-aware IGPs. It would be advantageous for Communications Service Providers (CSPs) to support an MPLS Multi-Topology (MPLS-MT) environment. The benefits of MPLS-MT technology are features for various network scenarios, including:

                    LDP Extensions for Multi-Topology

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.
