Site to Site VPN advice needed

[monroeatc]

Hi, new to Meraki. 

We have a client expanding from 2 to 3 locations, with the newest location designated to be the HQ. We have the added benefit of supporting all 3 locations, and upgrading each location with new Meraki equipment. We have an MX100 at the HQ, and MX68 at each of the other 2 locations. HQ has 50 users, but planning to increase up to 250 soon. The other two locations have fewer than 50 users, with no plans to increase. HQ will be running a Windows server application, all sites need to access. 

My question, since we have the ability to dictate local subnets, what is the best practice and/or common configuration for this site to site vpn, knowing the number of users and equipment in play?

Lucky for you, with all sites being Meraki, you can simply use AutoVPN.

I quite like assigning /22's supernets to office locations.  They lets you have up to 4 x /24's subnets per site. Sample uses for them are:

* Servers

* Workstations

* VoIP

* Internet WiFi

Even if you only need a single /24 now, it's nice being able to accomodate changes without a big renumbering.
