Abstract
A segment within a virtual network is identified as being supported by a segment bundling device. The segment within the virtual network supports a first host connected to a first bridging device and a second host connected to a second bridging device. The segment bundling device is used to receive virtual network address information describing the virtual network segmentation identifier (ID) for the segment used for receiving virtual network traffic for the first and second host. A segment bundling table associating a bundle ID with the virtual network segmentation identifier based on the upper ID and the lower ID of the virtual network ID is generated by the segment bundling device. The segment bundling device is used to distribute the segment bundling table to traffic forwarding devices in the virtual network that interface with the first bridging device and the second bridging device.
