Interconnect Between Warren Full Installations

Legend:

Warren uses Tungsten Fabric (TF) as an SDN solution
TFc is essential component in both full- an partial Warren installations
TF control node is central unit of SDN
Every hypervisor (host) has vRouter instance installed
Each vRouter creates separate VRF (Virtual Routing and Forwarding table) for each particular subnet for which a Virtual Machines are created.
Full mesh MP-iBGP is configured by TF between itself and all vRouters
Overlay tunnels (currently only MPLS over GRE) are used to carry data plane traffic
TF Control node acts as Router Reflector in whole MP-iBGP domain
Site Edge Router acts as SDN Gateway
