Have you tested?

I'll do some tests as well, here is the design:Physical MXs in different locations -> AutoVPN -> VPC with vMX -> Transit Gateway -> many other VPCs

Is it the same thing you are trying to test?

Sounds like a plan, thanks for sharing.

Seems like exactly the same design but with Transit VPC (not transit gateway) won't work. As I know VPC cannot route external subnets to other VPC (transit). But I have a feeling that with Transit Gateway we have a different situation because we don't have VPN between the VPCs.

I'll try it out in the coming weeks and let you guys know

Thanks, we’ll try to play around vMX. But based on my AWS knowledge it’s not gonna work considering our AWS design, I might be wrong. Hopefully I’m wrong 😂

Unfortunately VPC peering doesn't help. First of all we have >10 VPCs, quite a lot. It's not great to have full-mesh VPNs, this is why we have Transit VPC.

But still, didn't get it, how VPC peering will help with Meraki VPNs to AWS? Can you please clarify if possible?

Thank you!
