Hello everybody.
I have one question, beacause I think the doc isn't clear.
When I make a IPsec tunnel between vMX and third-party with All network tags in Availability. All my remote sites (networks) in my organization bring up a tunnel with a non-meraki equipment? Or is just for routing?
I have with vMX as hub, and MX67 in remote sites, all networks in the same organization.
If I only bring up a IPsec tunnel tagging vMX network in Availability, other sites can reach the non-meraki network? Is it neccesary to install the network in VPN settings to advertise to the spokes?
My requirements is only have one tunnel between vMX and non-meraki, and all the spokes in the same organization can access to te remote non-meraki network.

On the doc I read
- Availability settings to determine which appliances in your dashboard organization will connect to the Non-Meraki peer. Only networks with a network tag associated under Organization > Overview can be selected in the availability section.
What is 'connect' mean? Establishing tunnel or a routing adversited for the hub?
Thank you for reading.
Regards.
