Explanation

Router mode (also called routed mode) places the load balancer as a Layer 3 device in the network path. The client-facing side has one IP subnet hosting the Virtual IP addresses (VIPs), and the server-facing side has a separate IP subnet hosting the real application servers. This discrete IP segmentation is a fundamental characteristic of router mode and satisfies the security requirement for isolated IP segments. In contrast, transparent/bridge mode keeps VIPs and servers on the same IP subnet (Layer 2), which would not meet the requirement for discrete IP segments. Pass-through mode does not perform full load balancing.
