Question

Which controller is the single plane of management for Cisco SD-WAN?

Roslyn · Accepted Answer

D) vManage
The primary components for the Cisco SD-WAN solution consist of the vManage network
management system (management plane), the vSmart controller (control plane), the vBond
orchestrator (orchestration plane), and the vEdge router (data plane).
+ vManage -- This centralized network management system provides a GUI interface to easily
monitor, configure, and maintain all Cisco SD-WAN devices and links in the underlay and overlay
network.
+ vSmart controller -- This software-based component is responsible for the centralized control
plane of the SD-WAN network. It establishes a secure connection to each vEdge router and
distributes routes and policy information via the Overlay Management Protocol (OMP), acting as a
route reflector. It also orchestrates the secure data plane connectivity between the vEdge routers
by distributing crypto key information, allowing for a very scalable, IKE-less architecture.
+ vBond orchestrator -- This software-based component performs the initial authentication of
vEdge devices and orchestrates vSmart and vEdge connectivity. It also has an important role in
enabling the communication of devices that sit behind Network Address Translation (NAT).
+ vEdge router -- This device, available as either a hardware appliance or software-based router,
sits at a physical site or in the cloud and provides secure data plane connectivity among the sites
over one or more WAN transports. It is responsible for traffic forwarding, security, encryption,
Quality of Service (QoS), routing protocols such as Border Gateway Protocol (BGP) and Open
Shortest Path First (OSPF), and more.
