Devices, systems, methods, and processes for facilitating power savings by entering a lower-power state. Often, the lower-power state is able to power down more components than is typical but relying on a physical connection between the various network devices to retain the connection. This connection can be via a PHY connection in accordance with the OSI model. Additional components on the device can be powered down while avoiding the destruction of connections to neighboring network devices. In this configuration, the device in the lower-power state can wake and resume operations in a suitable timeframe. Often, this can be configured as a high-availability pair that can have one device active and another in deep standby to provide a failover configuration that utilizes less power than would otherwise be utilized in a traditional system. This can be expanded to devices that communicate wirelessly, but have a physical connection to a shared device.

The embodiment of the invention relates to a point-to-multipoint layer 2 element network extension on a layer 3 network. Techniques are disclosed for session-based routing within an OSI model L2 network extended over an L3 network. The L2 network connects the first client device to the first router and the second client device to the second router. And the L3 network is connected with the first router and the second router. A first router receives an L2 frame from a first client device destined for a second client device. The first router generates an L3 packet including an L3 header specifying L3 addresses of the first router and the second router, a first portion of metadata including L2 addresses of the first client device and the second client device, and a second portion of metadata including L3 addresses of the first client device and the second client device, and forwarding the L3 packet to the second router. The second router restores the L2 frame from the metadata and forwards the L2 frame to the second client device.
