Can you give a scenario where I would want to use multiple dummy's instead of just adding/removing addresses to the loopback interface? I can't use a dummy interface for "real" packet processing since it just drops the packet. If the use case is to make addresses from loopback/dummy available on other interfaces, then does it matter if those addresses originally came from a single lo or multiple dummy's? Cheers, Wilhelm.
