Which component is responsible for routing protocols such as BGP and OSPF in a Cisco SD-WAN solution?

The vSmart Controller is responsible for the Overlay Management Protocol (OMP) within the SD-WAN fabric, not for directly running traditional routing protocols like BGP or OSPF with local networks.

The vBond Orchestrator's role is initial device authentication and orchestration, not route exchange via BGP or OSPF.

vManage is the management plane for configuration and monitoring, not a routing participant for data plane protocols like BGP or OSPF.

The WAN Edge Router is the component responsible for running traditional routing protocols like BGP and OSPF on the service-side VPNs to exchange routes with the local network infrastructure. These routers act as the gateway between the enterprise LAN and the SD-WAN overlay, redistributing learned routes into OMP and vice versa to facilitate connectivity across the fabric.
