Explanation

Cisco ACE (Application Control Engine) in active/passive mode (B) intentionally places duplicate IP addresses on the same network. In an active/passive deployment, both the active and standby ACE appliances share the same virtual IP address (VIP) for server load balancing. When a client connects to the VIP, the active device handles traffic; if it fails, the standby assumes the same VIP seamlessly. HSRP (A) and VRRP (C) also use virtual IPs shared between devices, but they use a virtual IP distinct from the physical interface IPs - ACE is the specific design scenario known for having duplicate real IPs co-existing on the same subnet.
