How is redundancy achieved among Cisco vBond Orchestrators in a Cisco SD-WAN deployment?

Redundancy for Cisco vBond Orchestrators is normally achieved by mapping the IP addresses of multiple vBond instances to a single DNS name. WAN Edge devices use the configured organization name and vBond DNS name during onboarding to resolve and contact an available orchestrator. This design allows several vBond nodes to be deployed across different locations or availability zones while giving the edge device a consistent bootstrap target. If one vBond is unavailable, DNS resolution can return another reachable vBond address, allowing control-connection orchestration to continue. Selecting only the closest vBond is not the redundancy mechanism described here, and deploying a single vBond creates an avoidable single point of failure. The answer that says WAN Edge routers are configured with all orchestrators by IP address and priority does not represent the common DNS-based design model. In production, the DNS record, certificates, firewall policy, NAT behavior, and controller reachability should all be validated so that WAN Edge devices can reach multiple vBond instances during onboarding and after failures.
