3. Configure the IP interfaces on Alteon. Alteon must have an IP route to all of the real servers that
receive switching services. For load balancing the traffic, Alteon uses this path to determine the
level of TCP/IP reach of the WAN links.
Step 2—Configure the Load Balancing Parameters for ISP Routers
Configure the ISP routers with load balancing parameters: real servers, group, metric, and health.
1. Configure IP addresses for WAN link routers.
Proxy is disabled on the real servers, so that the original destination IP address is preserved.
