I'm looking to set up a Firepower 2110 Threat Defense using the Firepower Device Manager GUI.
I have a single outside interface set to the main ISP that all traffic is currently routing through, but also have a secondary outside interface for a second ISP.
The secondary interface shows that the link is up, and it acquired an IP address, but what I can't find in the FDM is any way to have it fail over to the second WAN when the first is unavailable.
I've found countless guides on doing this using SLA, but unfortunately, neither the CLI, nor the FlexConfig on the FP2110 seem to allow those commands.
Is there any good method to configure a simple ISP failover on this device?
