What is active/active failover?
Active/Active failover is only available to security appliances in multiple context mode. In an Active/Active failover configuration, both security appliances can pass network traffic. In Active/Active failover, you divide the security contexts on the security appliance into failover groups. A failover group is simply a logical group of one or more security contexts. You can create a maximum of two failover groups on the security appliance. The admin context is always a member of failover group 1. Any unassigned security contexts are also members of failover group 1 by default. We have already seen the configuration for Active/Standby failover in the previous article. This article focuses on how to configure an Active/Active Failover configuration on ASA Security Appliance. Network Diagram (Physical Topology)
