Ignition MQTT - Redundant Gateways and Failover of MQTT traffic?

Ignition Modules MQTT Modules
1

Hoping someone in the forum can assist with a question I have around Ignition Gateway Redundancy and MQTT. We are looking at using Gateway Redundancy for uptime/resiliency/maintenance purposes, but have some questions around how MQTT traffic routing happens at the Edge Nodes when a failover occurs from Primary to Backup Gateway? Since the Backup Gateway will be on a different IP how can traffic be redirected (from Edge Nodes) to the Backup Gateway when a failover occurs?

Do you have any helpful hints as to how to best architect this so we don’t lose data on a failover condition to the Backup Gateway?

I’d recommend starting with the basic tutorial. It covers much of what it sounds like you’re trying to do: Advanced: MQTT Modules in Redundant Ignition Environment - MQTT Modules for Ignition 8.x - Confluence

Thanks Wes. I am getting old as I recall looking at this link before, but didn’t retain it in my aging brain. I will give it a good read this time. Thanks again Wes. Cheers, Chris
