Figure 12 shows how two Server Load Balancers and three servers form a
redundant Web service. Server Load Balancer 1 is the Primary server load
balancer which actively handles client requests sent to the VIP. Server
Load Balancer 2 automatically recognizes the settings on Server Load
Balancer 1 and is configured for the same service.
