Difference between loopback and dummy interfaces for use in Linux routing

2018-04-27 Thread Wilhelm Schuster
Hi, I’m learning about IP-networking and am in the process of setting up a Linux router using bird. During my research I’ve come across the usage of loopback interfaces. I could gather that this is done, because Ethernet interfaces for example (in contrast to loopbacks) can go down making the a
