Multiple WAN VPN to Multiple WAN VPN; ideas appreciated

I have a build-out for a multi location retail store. Need to connect 3 satellite stores to one main store via Ipsec VPN. Complication is that the owner wants dual wan failover at all stores. This means if wan 1 at satellite 1 goes out and wan 2 at Main office goes out they should maintain a vpn connection on the WAN interfaces that are still up.

I think I can figure out how to connect 2 vpns from each location to the main store, but have no idea how to make a vpn WAN agnostic. I just don’t know where to start. Any suggestions would be greatly appreciated.

GRE or EoIP over ipsec with ospf will work well for this.

Thank you very much. Will research that setup.

I am not a network engineer and only work with relatively simple networks. No cisco training, no routeros training. I had never even heard of OSPF until now. In your opinion, is this going to be too complex for someone like me to handle? Or is it more simple than it seems?

Would it be possible to pay someone to configure these units remotely?

Thanks again.

For 4 stores you can get away with static routes. But if you are going to be adding stores later OSPF will be your best friend.

This is the same thing we do with out company network. It’s really not that complicated and you should be able to figure it out.
