PA and ASA n route mode

L4 Transporter


I have the below topology  

PA and  ASA are in routed mode . 

The first question is the design is valid? 

I am facing a problem in this design 

ASA says the secondary is failed  ,primary asa says the secondary and dmz zone interface failed 







L3 Networker



As per diagram you can still optimize your design with full redundancy towards ISP(CE) side via the layer-2 switch and configure the route or path monitor and provide routing redundancy with static and also firewall redundancy with PAN firewall.


as per given info here how you are doing secondary and DMZ failover. 


As per understand I can say that if you are monitoring inside /DMZ links then if anyone link fails from primary PA firewall to ASA then you can shift traffic to the secondary firewall (PAN) and secondary ASA.



Best Regards,

ASA interfaces that communicate for failover need to be on the same L2 segment. ASA also needs a failover interface.

Unless you've left some things out of the drawing, I wouldn't expect this to work. Consider putting some L2 devices between the layers.
