Reacting to Link Failure

Is there any way for other programs to listen for Bird events regarding Link Failure (IE: OSPF/BFD dead neighbor)? Bird is great, but the modems and device drivers I am working with are not. I can get some pretty odd ‘zombie’ states on network interfaces, and the BFD session going down is often the best indicator something bad happened. I was hoping to get that information from bird and take actions to fix it. -Liam Kelly
