Summary
In this application note, the setup of Linux Network Namespaces was shown. It also explained how to use this scheme to provide virtual Ethernet interfaces that work independently from the underlying phyiscal interface. This allows to run application like PROFINET devices on the same physical device as IP based services like webserver or SSH consoles.
