SDWAN-ADVPN-BGP in multiple layer network

[shiryunaga]

I am working on a project that involves creating a SDWAN in a complicated situation. (See picture below). As you can see, I need to create another ADVPN.

Would it be possible for someone to assist me? Thank you

Hello @shiryunaga 
I would suggest you check this KB article: https://community.fortinet.com/t5/FortiGate/Technical-Tip-Fortinet-Auto-Discovery-VPN-ADVPN/ta-p/195...

Download the pdf attachment and it has explained about the Dual Region topology.

Dear Rajneesh thx u for reference

But i wanna ask, my topology is different using spoke from ADVPN A as hub B [See Picture Below]

i already setup ADVPN A but have no idea how to setup dynamic route between ADVPN A dan B

- can i use same AS BGP between ADVPN A and B ?

To set up SD-WAN with ADVPN and BGP in a multi-layer network, configure ADVPN on the hub and spoke routers for dynamic tunneling, and use BGP for dynamic routing between sites. Ensure each layer's routing policies are defined for optimal traffic flow and failover. Test the setup to confirm proper connectivity and routing between all spokes.
