Deployment Meraki MX100 and MS250 switchs

[HShanata]

Hello, We just moved to Meraki devices for our network, 1 MX100 and 8 MS250

What is currently setup is  each 4 switches are connected as physical stack ( 2 x 4 MS250 ) stacking cables.

Each stack connected to the MX100 with 1 uplink. 

I setup the VLANs routing on one stack and everything working as it should.

when I connected the 2nd stack and give one of the ports a Vlan number it took the IP and its working fine.

What I found that all the 2nd stack switches have RSTP enabled and passing traffic ( I think ) from the uplink of the 1st stack as its the one that have routing enabled . 

everything seems to be working fine but want to know what is the best way for this configuration.

The main stack is Suite 300 and the not routed one is Suite 200

Typically I would make one switch stack the "core" switch stack. I would then connect the MX and the second switch stack to that.  I would give the "core" switch stack a spanning tree priority of 0.
