Each site will have a failover WAN. I am wondering about UNIFI Magic SD-WAN mesh VPN, if one site’s internet goes down, then the fail-over picks up, will it reconnect or do i need to use the Hub & Spokes.
I have been doing some research, but i have been getting mixed results.
I have not tested it because I don’t have a failover, but there is a check box when setting up the SD-WAN to use the second WAN as a fail over.
Ok. Thank you, Tom. I went to UNIFI community and asked the question there as well. I tried their UNIFI GTP and it gave me this info: Yes, UniFi Magic SD-WAN Mesh VPN will automatically reconnect when the primary internet goes down and the failover WAN takes over. Additionally, it will automatically switch back to the primary internet when it reconnects. This functionality is supported in both Mesh and Hub & Spoke topologies.
Key points from the context:
-
Failover Support: Site Magic VPN will stay connected even if a gateway’s WAN IP address changes due to failover. The new IP address is automatically updated on the other gateways, ensuring the VPN remains operational.
-
Topology Choice: You do not need to use the Hub & Spoke configuration specifically for this functionality. The Mesh topology supports automatic reconnection as long as the failover WAN is properly configured.
I will have to try it and let the group here know the results.

I wish they had implemented ISIS for the Site Magic VPN so that OSPF could still be used for internal routing.
I have implemented SD-Wan Mesh and I did a test when the primay WAN went down and the fail over to the secondary WAN while i was pinging the other sites. when it was transitioning from the primary to secndary i only lost 3 pings and that was a quick switch over. So it was a success. I hope this help out someone who has a small network.
