Abstract
A bridged gateway (BG) coupled to a local area network (LAN) receives a layer 2 frame from a device coupled to the LAN. The BG determines that the layer 2 frame is addressed to a network gateway router that provides layer 3 routing services for the LAN. The BG forwards, to the network gateway router via a layer 2 tunnel, the layer 2 frame. The BG starts a timer that corresponds to the device. The BG determines that the timer has elapsed and no response to the layer 2 frame has been received by the BG. In response to determining that the timer has elapsed, the BG sends to a destination, an alert, the alert indicating that the device has not received a response to a message destined for the network gateway router.
