(an internal 16-bit subnet). The cluster's public IP address is 1.2.3.4, which is the virtual IP
address configured on the load balancer.
The User Agent, UAC A, with IP address 2.3.4.5 never sees the internal IP addresses configured
for the WebLogic SIP Server cluster. Instead, it sends requests to, and receives responses from
1.2.3.4.
The sections that follow discuss configuring the WebLogic SIP Server cluster and load balancer
for this example system.

WebLogic SIP Server Configuration
The WebLogic SIP Server cluster configuration specifies the public address as 1.2.3.4, and the
public port as 5060 (see “Configuring Load Balancer Addresses” on page 1-3) for each engine.
The default route on both WebLogic SIP Server engines points to the load balancer's 10.1/16
network interface: 10.1.3.4. The WebLogic SIP Server (servers WLSS 1 and WLSS 2) routing
table is shown in Listing 3-1.
