SYSTEMS AND METHODS FOR PROVIDING VLAN-INDEPENDENT GATEWAYS IN A NETWORK VIRTUALIZATION OVERLAY IMPLEMENTATION

摘要

An information handling system is provided. The information handling system includes a first hypervisor running on a first server and a second hypervisor running on a second server. The first hypervisor manages a first virtual switch and has an overlay forwarding table in memory supporting at least one virtual machine, while the second hypervisor manages a second virtual switch and also has the overlay forwarding table in memory and supports at least one other VM. The information handling system further includes a plurality of gateway devices coupled to the hypervisors. The gateway devices share a floating address and are configured to export a host route, associated with the address, into a corresponding entry in an underlay routing table to redirect network traffic from a first gateway device to a second gateway device.
