Has anyone attempted to create a site to site VPN with the Oracle cloud. We need to set this up however some of the documentation I'm finding is not pointing me in the right direction. Setup : 9 sites. All using MX appliances in routed mode(they are edge device as well) with 2 ISPs in load balance. Site to site Mesh all sites using AutoVPN. Requirement : Create an IPSec Tunnel to Oracle VCN. All sites need access to the resources on the other side of the tunnel. Issues / Questions : 1. Site to sites scope : If all networks are set for the scope will each unique MX try to establish a IPSec tunnel to the endpoint from each public IP resulting in 18 unique IP Sec tunnels 2. Routing : From the documentation I read if you don't have subnets "advertised to VPN" the tunnel will not come online and that the subnets on each side have to match. The oracle side would be using the summary route for the network however ourside would not be advertising the full summary route because I can't add that to any one site. Is this best accomplished with a concentrator (IE another Meraki MX behind my current pair)?
