Table 58 - Configuring WAN Link Load Balancing with SLB, page 647 provides an overview of
configuring simple WAN load balancing with SLB. All definitions for this example refer to Figure 105
- WAN Link Load Balancing with Server Load Balancing, page 646.
Step 1—Configure Basic Parameters
This step includes configuring VLAN, interfaces, and defining gateways per VLAN. Gateways per
VLAN is recommended if you have not configured other routing protocols. Configure a default
gateway per VLAN for each ISP.
1. Assign an IP address to each of the ISP links. The WAN links in any given real server group must
have an IP route to Alteon that performs the load balancing functions. For this example, the two
ISP links are the following IP addresses on different IP subnets:
2. 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.
3. On Alteon, configure VLANs.
