Displaying GSLB information

1

In this example, ServerIron ADX slb-1 is the active ServerIron ADX for VIPs 209.157.22.100 and 109.157.22.101 and ServerIron ADX slb-2 is the default active ServerIron ADX for VIPs 209.157.22.103 and 209.157.22.104. Although this example has both VIPs for a host active on the same ServerIron ADX, you can just as easily configure the VIPs so that both ServerIron ADXs have active VIPs for the same host.
