<IP address> is the IP address for which you are assigning a weight. <weight> is a value from 0 to 100. The default value is 0.

Implementing the weighted site metric
You can configure the ServerIron ADX to distribute SLB traffic among GSLB sites based on weights configured for the sites. The weights determine the percentage of traffic each site will receive in comparison with other sites, which may or may not have weights.
NOTE
You cannot use the weighted site metric if the weighted IP metric is enabled.
You assign weights to GSLB sites. Each GSLB site may consist of one or more ServerIron ADXs, but the weight is applicable to the site as a whole.
The GSLB ServerIron ADX uses relative percentages in order to achieve 100% total weight distribution, as shown in Table 5 and Table 6. In Table 5, the total of the Configured weighted site metrics (second column) is 100. The last column shows that the GSLB ServerIron ADX distributes the traffic to the IP addresses exactly as configured. In this example, traffic distribution is straightforward because the total weight of all three GSLB sites equals 100.
