Abstract:
Enhanced VPN (VPN+) aims to provide enhanced VPN service to support
some application's needs of enhanced isolation and stringent
performance requirements. VPN+ requires integration between the
overlay VPN and the underlay network. A Virtual Transport Network
(VTN) is a virtual underlay network which consists of a subset of the
network topology and network resources allocated from the physical
network. A VTN could be used as the underlay for one or a group of
VPN+ services.
In some network scenarios, each VTN can be associated with a unique
logical network topology. This document describes a mechanism to
build the SR based VTNs using IS-IS Multi-Topology together with
other well-defined IS-IS extensions.
