Abstract
Systems and methods for stretching a subnet that do not require level 2 (L2) communications to be handled are provided. A user may gradually migrate VMs or applications instead of migrating an entire subnet at one time, may fail-over specific VMs without failing-over an entire subnet or renumbering IP addresses, may deploy applications to the cloud without the need to create a VPN, or may enable hybrid network connectivity without modifying routes or (re)configuring edge routers, among other benefits. The domains over which the subnet are stretched include a virtual gateway which is associated with the layer-3 (L3) addresses of the other domains. L3 communications within the domain are routed within that domain, and L3 communications within the subnet in another domain are intercepted by the local gateway, are passed to the remote gateway of the other domain, and are forwarded to the destination while leveraging L3 communications.
