The document describes how to configure active/active failover on Cisco ASA firewalls. Key steps include: 1) Configuring both ASA devices in multiple context mode. 2) Creating failover groups and assigning contexts to each group. 3) Configuring failover and stateful failover interfaces on each device. 4) Assigning IP addresses to interfaces in each context. This allows both devices to remain active and share the load, improving firewall throughput and availability.
