Is that transparent? What bonding driver? And no, a link failing is *not* transparent. It will lead to intermittent connectivity problems, as the multipath routing code will randomly keep selecting the failed link as well as the one still working. You will have to do active monitoring. Yes, polling. Unfortunately. Let's all hope for IPv6 and true NUD...
