摘要：
In one embodiment, a particular device determines a selected link from the particular device toward a root device in a computer network, wherein traffic destined away from the root device via the particular device utilizes the selected link in reverse. By monitoring a link quality of the selected link in reverse based on received traffic over the selected link, the particular device may determine whether the link quality is below a lower threshold. In response to the link quality being below the lower threshold, the particular device activates use of keepalive messages from the particular device over the selected link.
