Usage Guidelines
You can configure a hub-and-spoke topology using transport gateway to operate as hubs. The resulting hub-and-spoke topology applies to all VRFs. This method avoids the need for complex centralized control policy.
The configuration requires only a few simple configuration steps: a single command each on (a) the Cisco SD-WAN Controllers serving a network, (b) a router that serves as a hub, configured as a transport gateway, and (c) edge routers operating as spokes.
Example
sdwanController(config)#system
sdwanController(config-system)#topology hub-and-spoke enable
