Abstract
A method, apparatus and program storage device for providing mutual failover and load-balancing between interfaces in a network is disclosed. An active virtual interface and a passive virtual interface are provided for each of a first and a second computer interface. The active virtual interface of the first computer interface is communicatively coupled with the passive virtual interface of the second interface. The active virtual interface of the second computer interface is communicatively coupled with the passive virtual interface of the first computer interface. Data flow is directed over each of the first computer interface-active virtual interface and second computer interface active virtual interface when the first and second computer interface is available, else data flow is directed to the active virtual interface and passive virtual interface of an available first or second interface.
