I have network A that is 10.1.10.0/24 I have network B that is 10.1.20.0/24

They are connected to each other via site-site VPN

Each network has a Hyper-V server. I’m wanting to failover one VM to another network if needed, without changing IP address. But if they are on different subnets, that’s where I get lost.

How would I make a device on subnet 10.1.10.x work on network B and vice versa?

Sorry, new to Meraki and networking in general, so not understanding how to make this happen. I’ve done a similar task via VLAN’S on the same firewall, but not spanning multiple networks like this. Plus, if I had both subnets on both firewalls, that would confuse things being that they are connected via VPN, because could have duplicate IP addresses, right?
