I'm trying to configure an Azure Site to Site VPN with redundancy over multiple WAN uplinks.

However, according to this:

This is not possible.

I've created a Route-Based VPN in Azure to a Cisco 2911 successfully. I am able to pass traffic, and I can add another S2S VPN to the same Virtual Gateway in Azure, but I cannot reference the same on-premise subnet. According to this azure document its just not possible still:

https://azure.microsoft.com/en-us/documentation/articles/vpn-gateway-multi-site/

Is there any way to make this work?

If not will AWS be able to do it? My goal is to provide redundant VPN links to cloud services hosting a backup of our DC/NPS.

Thanks for any input!
