create a new topology

[Meraki43]

We have to create a new network topology on our site. The devices are 2isp connected mutually, both MX85 (HA) active and passive, 2MX85 connected to a Cisco 2960X switch, and 3MR33 connected to the 2960X. We need to know the LAN failover.

I'm not quite sure what you're asking, but it sounds like your 2960X is your single point of failure in this scenario.

For true redundancy and failover, you probably want to have another in a switch stack, and connect one MX per switch and spread the AP's between the two switches.

Thanks for your replay. I plan to implement the 2960x stackable switch so it will have more redundancy. This is my concern. Could you please share your suggestions?

If it simply says I need to create the best redundant topology, The devices are the 2ISP, 2MX85, Cisco 2960x stacable switch, and 3MR33. Could you please share your suggestions to create it?

With the design you've got, and having stacked switches it sounds like you have fairly well covered redundancy. Keep in mind that for routed HA for your MX's, they'll need multiple IP's in the same subnet for the WAN connections.
