The vBond Orchestrator in Cisco SD-WAN is responsible for authenticating and orchestrating connectivity between the SD-WAN edge devices (vEdge routers) and the vManage and vSmart controllers. The reachability of vBond is crucial for the initial device onboarding and ongoing operations.
DNS (Domain Name System): vManage resolves the vBond reachability using DNS. By using a Fully Qualified Domain Name (FQDN) for the vBond orchestrator, the system can dynamically resolve the vBond's IP address, which allows for flexibility in managing the vBond's location and redundancy.
Functionality: When a new edge device comes online, it contacts the vBond orchestrator using its FQDN. DNS resolution translates this FQDN into an IP address, allowing the device to establish a secure connection.
