Hi Team,
Greetings,
We have a requirement like client want to know about the FW HA across different location in "Active-Active" mode.
For example, PA Model: PA-3430
What are requirements for having fw cluster spread across different GEO locations (latency, delay, etc)? Distance between two locations is 5-10 KM.
Is this recommended at all by PA? If yes, what kind of link is required for HA connectivity (L3, L2) for "Active-Active"?
I guess Client may consider Multi-VSYS environment too.
Would it possible to make this happen? Please share your thoughts.
Thank You

Hi @BrajeshPatel ,
Yes, it has been done many times as long as the latency is fine. PANW unofficially recommends 20ms or better between firewalls. Customers have reported it works fine with 80-120ms. Check out this video starting at 1 hour 14 minutes. Bandwidth should also be considered. https://www.youtube.com/watch?v=4hFQypgOAGk&t=4665s
