MX250 - Maximum Z1/Z3 connections

[Lagcat]

Hello

due to the fun of the current virus spreading out company is looking to purchase a large amount of Z3 devices to hang off the back of our MX250 with 2x1GB lines

is there any limit I should configure apart from the 1GB vpn throughput?

will I reach any limit of the site-site connections?

we are looking to purchase anywhere between 100-800 devices - mainly going to be a small amount of application and voice traffic

Cheers

Jake

Keep in mind the tunnel count and recommended tunnels. A good guide here:  https://www.willette.works/meraki-mx-sizing/

Indeed, what @ww said. In the case of the MX250 the maximum number of tunnels is 3000, so you should be fine with 800 Z1/3's.

Edit: @ww correctly pointed out to me that the maximum recommended number of tunnels for the MX250 is 1000. If your MX is using dual uplinks that means you'll need 2 tunnels per Z1/3. So 800 would result in 1600 tunnels. I still think you will be fine with the 800 as you'll still be under 3000 tunnels which is the max number of tunnels.
