Key components of the solution:
vManage Network Management System (NMS)—The vManage NMS is a centralized network management system that lets you configure and manage the entire overlay network from a simple graphical dashboard - in the data center.
vSmart Controller—The vSmart controller is the centralized brain of the Viptela solution, controlling the flow of data traffic throughout the network. The vSmart controller works with the vBond orchestrator to authenticate Viptela devices as they join the network and to orchestrate connectivity among the vEdge routers - in the data center.
vBond Orchestrator—The vBond orchestrator automatically orchestrates connectivity between vEdge routers and vSmart controllers. If any vEdge router or vSmart controller is behind a NAT, the vBond orchestrator also serves as an initial NAT-traversal orchestrator - in the DMZ.
vEdge Routers—The vEdge routers sit at the perimeter of a site (such as remote offices, branches, campuses, data centers) and provide connectivity among the sites. They are either hardware devices or software, vEdge Cloud router. vEdge routers handle the transmission of data traffic.
Domain ID: a logical grouping of vEdge routers and vSmart controllers. vEdge routers can connect only with the vSmart controllers in their own domain.
Site ID: a physical location within the Viptela overlay network, such as a branch office, a data center, or a campus. Each Viptela device at a site is identified by the same site ID
System IP Address: similar to the router ID on a regular router
TLOC: transport location, identifies the physical interface where a vEdge router connects to the WAN transport network or to a NAT gateway.
OMP (Overlay Management Protocol): runs inside the DTLS connection and carries the routes, next hops, keys, and policy information needed to establish and maintain the overlay network. OMP runs between the vEdge router and the vSmart controller and carries only control information.
