Hello, We are bringing a second MX84 online as a warm spare, the problem is that our ISP gives us one /30 address and we do not want to use a breakout switch in front of the MX84's but do it in the switch stack. So, I created a new vlan 666, brought the ISP into port one of switch 1 with VLAN 666, then also included port 2 and 3 in switch one for VLAN 666 to wire into WAN 1 of each MX, essentially creating a hub to split the ISP. I'm unsure when creating the vlan if I should use "same or unique" setting in the subnetting. If I use same I need to enter the MX IP, is that the primary MX IP? Thanks in advance for any help.

I am adding a second data center for redundancy and a new pair of Meraki MX450's. Data Center 1 has two MX 450's and will be adding 2 new 450's to the new data center. The first ones run our wireless networks for 5 different campuses. The new MX450 will be available in the event we have an outage. I have read the design guide but I'm not 100% certain of the following question and don't want to cause an outage so... The current MX units are running in passthrough mode. So, 1. When adding the new MX's do I create an additional network in the same organization? The current MX units are in combined network mode. 2. How do I specify what MX units to use, the new ones or the old ones how is that priority set? 3. Do the MX units in different data centers need a heartbeat to each other even though they are on different IP networks? 4. How do they talk to each other and not take over the traffic? Thanks for any design help
