I have a topology as in the picture. It is designed to be a factory network. 2 ASAs in a failover cluster border the whole LAN. And it is pretty much clear how to configure them: outside interface to ISP, inside subinterfaces to different VLANs. But, I need ti have also HA clusters to border Workshops from the rest of the LAN. And I cannot understand, how exactly to configure ASAs. I thought to put them in a transparent mode. But in any case, the interface (Outside) from ASA to switch DSW3-RING need to be trunk, isn't it?
I got really confused thinking about it. Thanks in advance for help]2
