Doesn't babeld notice when an interface goes down, and immediately tries to find another route? (well, unplugging a cable is not the same as going down, but I guess the kernel could tell us anyway) If I recall correctly, Quagga already watches interfaces for link-layer events, so quagga-babel probably benefits from it. On a related note, I once tried to use nl80211 [1] for detecting 802.11 association/deassociation events: basically, an elaborate version of running « iw dev wlan0 station dump » at regular interval. The goal is to immediately notice when a neighbour disappears, by looking at the link layer. Unfortunately, I never managed to get it to work properly, netlink is pretty arcane :/ [1] http://wireless.kernel.org/en/developers/Documentation/nl80211
