Goal

When the public interface fails, VIP fails over to the surviving node. However, multiple interfaces can be defined for VIP to allow it to fail-over to another interface in the same node before failing over to the surviving node. This capability provides redundancy needed for high availability.

Although NIC bonding, IPMP, ether-channel, and other aggregation method provided by OS give the same fail-over capability, the ability to define multiple NIC cards for VIP provides additional flexibility.
