The vSmart controller is responsible for managing the control plane in a Cisco SD-WAN deployment, including routing information exchange, policy enforcement, secure control plane connections, overlay topology management, service chaining, and analytics. Its role is central to maintaining the overlay network’s efficiency, security, and policy compliance across distributed sites.
In an SD-WAN deployment, the vSmart controller is primarily responsible for: D. Manage, maintain, and gather configuration and status for nodes within the SD-WAN fabric The vSmart controller acts as a centralized brain of the SD-WAN architecture, responsible for orchestrating and managing the SD-WAN fabric. It's involved in the control plane operations, managing the configuration, policies, and status information for the network elements, including vEdge routers. Specifically, the vSmart controller performs tasks such as policy distribution, control plane intelligence, configuration management, and providing routing information to the SD-WAN edge devices (vEdge routers). It helps in making forwarding decisions and ensuring that the SD-WAN fabric operates according to the defined policies and configurations across the network.
Incorrect, vSmart does not gather configuration information for nodes, but rather control plane information.
