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 connectivity and the characteristics provided the underlay network. A Virtual Transport Network (VTN) is a virtual underlay network which has a customized network topology and a set of network resources allocated from the physical network. A VTN could be used as the underlay for one or a group of VPN+ services. The topology of a VTN can be defined using Flex-Algo. In some network scenarios, each VTN can be associated with a unique Flex- Algo, and the set of network resources of the VTN can be instantiated as sub-interfaces or member links of the L3 interfaces. This document describes the mechanisms to build the SR based VTNs using SR Flex-Algo and IGP L2 bundle with minor extensions.
