Meraki MX100 Active and Passive Configuration and Setup

[Tem]

I have two meraki MX100, these are new devices and i already registered them into one network name.

My question is How will I going to setup the network connection between two MX100 and DSL modem (ISP).

What will be the apps that needs to be enable on both devices?

I hope your DSL Modem can do the PPPoE job and provide DHCP IP on its LAN. Use a small switch, as known as 'WAN Switch' or 'Perimeter Switch' and terminate your DSL Modem there. Many DSL Modem have built-in switchports on its LAN. Connect both MX 'INTERNET' ports on the switch. If DHCP is Enabled, both will get IP and connect to cloud. If DHCP service is not available, you should configure manual IP as a destination to internet towards your GSM Modem.

Configure first MX as you need, then add second MX as 'Warm Spare' from 'Appliance status' page.

No not required since sync is performed through cloud.

This might be a useful read as well. I put that together as a way of documenting MX warm spare deployment best practices and considerations.
