Meraki MX HA with Layer3 Switch

Hi all,

 

Was wondering if I can cable two MXs in HA and a Layer 3 switch stack like the image? See the extra green lines.HA-Setup-Layer3.png

 

At the moment I only have one cable running between each MX and switch stack member.

 

Thanks.

Yes, just be sure to enable the STP on the switches. The MX doesn't support LACP, so enable the STP is a recommendation.

Awesome, thank you.

 

STP is already enabled on the stack.

 

Also, to add more complication to it, what if I run an extra cable between them for a Guest WiFi VLAN from the MX. See the red in the image.HA-Setup-Layer3-GUEST.png

I don't recommend this topology. I think that a trunk port is the best option.

 

Take a look at this.

Good to know, thanks.

 

A trunk port with VLAN10 as the Native VLAN and add the extra VLAN(s) to the trunk?

Yes, is the VLAN 10 your management VLAN?

Its the transit VLAN for the traffic from the switch stack VLANs out to the internet/SD-WAN
