We are planning to deploy FTD firewalls in HA in 2 different physical location (1-1) , Need some some suggestions on any limitations are best practices to deploy.
Guidelines are pretty much the same as ASA failover.
You need a low latency link with a "stretched VLAN" as the failover links need to be on the same subnet. Also the interfaces' addresses need to be on the same subnets.
