2 MX and a Switch for warm spare

Hello everyone from Spain.

 

I have a client who has an MS210-24, 2 MX67s and a public IP offered by his ISP. Is it possible to connect the two MX with warm spare using VLAN on the switch? The idea is ports 1-4 VLAN 10 and the rest VLAN 1. Connect the router isp in port 1 and the two mx in ports 2 and 3 for WAN and 5 and 6 for lan. Could you put the same ip-wan on both MXs using STP on the port?

 

Thanks and sorry for the google translation.

No, you can't set the same WAN IP on both MXes, the only way is using a NATed IP for WAN interfaces.https://documentation.meraki.com/MX/Deployment_Guides/MX_Warm_Spare_-_High_Availability_Pair

I am not a Cisco Meraki employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.

Take a look here for info / a slide deck regarding using a switch for lan and wan

As @alemabrahao says, each MX needs its own IP address.  Considering changing to a circuit with the ISP that comes with a /29, or using two Internet circuits.

Thank you for your response. As I already knew, I will have to convince the customer to hire a /29 or keep the second MX in a closet until I need it. 

It would not be a bad idea to implement the option of wan port off until the connection error and spare activation.
