What is a characteristic of vManage?
vManage leverages the overlay management protocol (OMP) to interface with WAN Edge devices. OMP is a protocol used to manage and control the routing information exchanged between the vSmart controllers and the WAN Edge devices, facilitating the creation and operation of the SD-WAN overlay network.
vManage => NETCONF => vSmart => OMP => VEdge While it's true that the vSmart controllers don't construct the data plane, answers A and B are clearly referencing vSmart.
Not D: Cisco vSmart it is belongs to control plane and it is the brain of the solution. It is responsible for enforcing the policies centrally. These policies are created on the vManage.
all answers are wrong, however the closeset one is D
For me its C bcoz vManage requires a public IP address to enable WAN Edge devices to discover and communicate with the components of the SD-WAN fabric. This is necessary for the establishment and management of the overlay network. Option D:- This characteristic is not accurate. vManage primarily uses NETCONF for communication with WAN Edge devices, not vSmart devices, to configure and manage the overlay network. A:- This characteristic is also not accurate. vManage primarily uses NETCONF, RESTCONF, and other protocols to communicate with WAN Edge devices, rather than overlay management protocols.
OMP is really for vSmart a.k.a. SD-WAN Controllers to communicate with each other and the edge devices. vManage (now SD-WAN Manager) uses NETCONF for its communications to the controllers, per the below link. Some quotes: "The NETCONF protocol defines a mechanism through which network devices are managed and configured. The SD-WAN Manager uses NETCONF for communication with SD-WAN devices, primarily over DTLS/TLS, but there are a few situations where NETCONF is used natively before DTLS/TLS connections are formed." "The Overlay Management Protocol (OMP), a TCP-based protocol similar to BGP, provides the routing for the overlay network. The protocol runs between SD-WAN Controllers and WAN Edge routers where control plane information is exchanged over secure DTLS or TLS connections." https://www.cisco.com/c/en/us/td/docs/solutions/CVD/SDWAN/cisco-sdwan-design-guide.html
It leverages the overlay management protocol to interface with WAN Edge devices1. Cisco vManage is a highly customizable dashboard that simplifies and automates the deployment, configuration, management, and operation for Cisco SD-WAN2. It uses the overlay management protocol (OMP) to communicate with vSmart controllers and WAN Edge devices, and to exchange routing, policy, and management information3. 1: Cisco SD-WAN Design Guide 2: Cisco Catalyst SD-WAN Manager (formerly vManage) - Cisco 3: SD-WAN API, Release 20.6 - Cisco DevNet
vSmart controllers do not directly build the overlay network data plane. The data plane is constructed by the WAN Edge devices (such as vEdge routers), which establish encrypted tunnels between each other to carry traffic across the SD-WAN fabric. These tunnels form the overlay network data plane, allowing efficient and secure communication between sites. So, while vSmart controllers handle control plane functions, the data plane is established by the WAN Edge devices.
