IPAT and service IP labels

IPAT manipulates the service IP label.

When IPAT via IP aliases is used, the service IP label or IP address is aliased or added as an additional address to the same network interface. That is, multiple IP addresses or IP labels are configured on the same network interface at the same time. In this configuration, all IP addresses or labels that you define must be configured on different subnets unless there is a single network interface per node. This method can save hardware, but requires additional subnets.
