Abstract:
1. A method of implementing control of multiple network devices, the multiple network devices being physically dual homed on a pair of gateways configured to provide interconnectivity between the multiple network devices and a routed Ethernet network, the method comprising the steps of: implementing, by each gateway, at least one virtual switch instance to represent the multiple dual homed network devices into the routed Ethernet network; and implementing at least one ring-based control protocol instance between the at least one virtual switch instance of each gateway and the multiple physically dual homed network devices to enable the virtual switches to coordinate representation of the dual homed network devices into the routed Ethernet network, wherein each gateway U-turns control traffic received from the dual homed network devices to implement a logical ring including the virtual switch instance of each gateway and the multiple physically dual homed network devices.
