BGP/MPLS IP VPN Data Center Interconnect
Luis M. Contreras, Luyuan Fang · 2014
This document discusses two categories of inter-connections of BGP/MPLS IP VPN and Data Center (DC) overlay networks. In the first category, DC overlay virtual network is built with BGP/MPLS IP VPN (IP VPN) technologies, the inter-connection of IP VPN in the DC to IP VPN in the WAN enables end-to-end IP VPN connectivity. In the second category, DC overlay network uses non IP VPN overlay technologies, the inter-connection of any overlay virtual network in the DC to IP VPN in the WAN provides end user connectivity through stitching of different overlay technologies.
