Configure load balancing using virtual IP and proxy ARP

Use these configuration steps for load balancing using virtual IP and proxy ARP.

Using Figure 2 as an example, the general configuration steps would be:

Configure a virtual TCP/IP interface
Using iSeries™ Navigator, create a virtual TCP/IP interface. The new Virtual IP interface wizard can be found at: Network > TCP/IP Configuration > IPv4 > Interfaces. Then right-click Interfaces and choose New Interface > Virtual IP.

For our example, you will enter an IP address of 10.1.1.7 with a subnet mask of 255.255.255.255. After you have created the Virtual interface, right-click the interface and select Properties. Click the Advanced tab and select the Enable proxy ARP check box.
Create TCP/IP interfaces for all of your physical LAN connections
Use the Create TCP/IP interface wizard to create your TCP/IP interfaces. The wizard is in iSeries Navigator and can be found at: Network > TCP/IP Configuration > IPv4 > Interfaces. Then right-click Interfaces and choose New Interface > Local Area Network. Complete the wizard for each of your LAN connections.

For our example, you will run the wizard three times entering the IP addresses of 10.1.1.4, 10.1.1.5, and 10.1.1.6 with a subnet mask of 255.255.255.0. After you have completed each interface, right-click the interface and choose Properties. On the Advanced tab, associate the interface with the Virtual IP interface you created in step 1. You can associate the interfaces with the Associated local interface select box.
