ABSTRACT:
One embodiment relates to a method of providing dual-homing in a Layer 2 switch. A determination is made as to whether a link is available to an upstream network on for a currently active port. If the link is unavailable, then the Layer 2 switch a) performs a switchover such that the currently active port becomes a newly passive port, and a currently passive port becomes a newly active port, b) clears entries in an address table of the Layer 2 switch, and c) spoofs MAC addresses out of the newly active link. Other embodiments are also disclosed.
