Active/Active Failover Overview
Active/Active failover is only available to ASAs in multiple context mode. In an Active/Active failover
configuration, both ASAs can pass network traffic.
In Active/Active failover, you divide the security contexts on the ASA 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. The admin context is always a member of failover group 1. Any unassigned security
contexts are also members of failover group 1 by default.
