Claim Text:
1. A method for providing a virtual overlay network, the method comprising: receiving a packet having a virtual local area network (VLAN) identifier (ID) at a first physical overlay switch located at an edge of an internet protocol (IP) network directly from a first virtual switch operating in a first hypervisor domain; encapsulating the packet with an overlay header using the first physical overlay switch; and tunneling the encapsulated packet to a second physical overlay switch via the IP network in response to a determination that a source of the packet is physically separated from a destination of the packet by the IP network, the second physical overlay switch being connected to a second virtual switch operating in a second hypervisor domain, wherein the first hypervisor domain is associated with a first hypervisor that is unable to communicate with a second hypervisor associated with the second hypervisor domain.
