Enhanced VPN requires integration between the overlay VPN connectivity and the characteristics provided by the underlay network. A Network Resource Partition (NRP) is a subset of the network resources and associated policies on each of a connected set of links in the underlay network. An NRP could be used as the underlay to support one or a group of enhanced VPN services. In some network scenarios, each NRP can be associated with a unique logical network topology. This document describes a mechanism to build the SR-based NRPs using IS-IS Multi-Topology together with other well-defined IS-IS extensions.}, }
