I am sorry if this is off topic.I was once demoed a network device that had two interfaces. The traffic would go through the device. If there was a power cut or some other malfunction there would be a relay that would physically bridge the two network interfaces so the traffic would flow as if it was just a network cable. Is anyone aware of such a network card or device?
You can also do this with any routing protocol by including a bypass link and declaring the bypass higher cost than the one through your potentially malfunctioning device. This has the benefit of not having to care about whether the nature of the failure will affirmatively trigger the bypass since it'd negatively triggered on the absence of packets.
