We are going to implement MX warm spare with two MX:es but we have only one ISP connection. I have checked a little on meraki docs but I can't find any design which cover this. We have two MX:es and two MS:es. So my thought on this is that I use a special vlan on the switches for wan interface, like I would dedicate port 1and 2 on both switches for ISP vlan and then connect that one ISP on one of these ports. Not so redundant but is this something that will actually work with Meraki?
