vMX on Azure

[SAM-Al]

Hi All,,,, our company has main AD and some VMs in Azure, I was thinking about using virtual MX there to connect to all our sites via AutoVPN, what is the best practice to do that? and is there any limitation with virtual Meraki MX like the mode, number for VPN tunnels ..etc?

The vMX is a good choice.

This is the deployment guide for Azure.

It can only run in VPN Concentrator mode.  It can easily do 250 tunnels.

I'm more familiar with Amazon AWS environments, where it can cope with 500 tunnels.

Thanks for help Philip, 

Actually same here, I'm familiar with AWS more than Azure, I'm looking for 300+ tunnels, do you think the vMX can support that? If not, do recommend any alternative solution??

My personal guess is yes.  I would do it.  Aaron Willette has test it to 500.

The "offical" Meraki documentation says it can do 250 (but it is very conservative).  So if you feel you don't want to take on this small risk then you would need to get a pair of them, and put half the spokes on one and half on the other.

Aaron also has a guide for doing this using templates.

That helps Philip, i think having a pair of them is a good idea.

Thanks again
