I need suggestions on how to design an ASA 5520 Active/Standby solution.
T1 coming in from ISP to patch panel (Disaster Recovery site that also hosts our webservers)
T1 -> ASA -> L3 Switches -> Servers
T1 connecting to a router or L3 switch
ASA Primary and ASA standby connected to a port on the L3 switch in the same VLAN
ASA Primary and ASA standby connected via a GigabitEthernet interface for the failover link
ASA Primary and ASA standby inside interface connected to L3 switch that has our webservers
We have two L3 switches which our servers are connected to...should each ASA connect to both switches? One switch per ASA? Both ASA's to one switch? Does it matter?
Is this correct? Or is my design flawed?
