Which SD-WAN component runs routing protocols such as BGP and OSPF?

The WAN Edge Router is the correct answer because it is the component responsible for connecting the SD-WAN fabric to the physical network infrastructure, including local area networks (LANs) and wide area networks (WANs). As such, it runs traditional routing protocols like BGP (Border Gateway Protocol) and OSPF (Open Shortest Path First) to exchange routing information with other network devices. The vSmart Controller establishes secure connections with the WAN Edge routers and distributes routing and policy information, but it doesn't run routing protocols with external networks. vManage is the centralized network management system for configuration and monitoring. The vBond Orchestrator is the initial point of authentication and authorization for all SD-WAN components.
