Question

Want to route traffic from a Spoke2 (Site2) which is connected to Spoke1 via point to point link. Spoke1 connect to Hub via ISP link. Currently Spoke 2 uses dynamic routing on the underlay to exchange networks with spoke1. Is there a way to create a overlay tunnel using SDWAN on this scenario from Spoke2 towards hub? any reference material is appreciated.

look into ADVPN and treat Spoke1 as a pseudo-hub for the topology.

| Hub1/2 |<----underlay ebgp----> | Spoke1 |<----ospf----> | Spoke2 |<----underlay ospf----> | Spoke3 |<---underlay bgp---> | Hub1/2 |

Spoke1 is required to carry traffic from spoke 2 and spoke3 towards hub1/2

Spoke 3 has to act as failover for spoke 1. We can have 2 overlay one at spoke1 and spoke3 but i cant figureout how to route

Spoke2 to hub (there is no requirement to send traffic b/w spokes. Only hub and spoke traffic)
