The IPMultiNIC agent manages the virtual IP address that is configured as an alias on one interface of a MultiNICA resource. If the interface faults, the agent works with the MultiNICA resource to fail over the virtual IP to a backup interface. If multiple service groups have IPMultiNIC resources associated with the same MultiNICA resource, only one group must have the MultiNICA resource. The other groups have Proxy resources pointing to it. You can use this agent for IP addresses on multiple-adapter systems.
