Hi,
Hi,
Thank you for the explanation.
What I’m struggling with is understanding the differences between both interface types (besides the obvious difference in packet processing) and when to use which.
My understanding is that it's not possible to add additional loopback interfaces on Linux. Instead dummy interfaces are added and removed on Linux like loopbacks are added and removed on other NOSs. (I know that you can create and remove loopback interfaces at whim on classic Cisco IOS.)
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.
