Redundant MX setup, 2 ISP but with only /30 link

Hi Guys

I would like to implement some redundany on our network with 2 MX appliances in Active/Standy.

The issue is we only a a /30 ip range from ISP1 and ISP2.

Would I be able to plug the WAN1 from ISP1 into the Active Meraki FW, and then ISP2 into WAN2 port on the standby Meraki FW? would this work ok?

Yes this will work. Both the active and standby MX are allowed to have different ISPs. But you can only use one ISP in this scenario at a given time.

I would talk to the ISPs to provide you with /29 subnets because that is needed for a really "clean" setup where both ISPs can be active at the same time.
