PS: The previous entry was only an example - please don't put too much energy into the details of the routes or such.
Even absolute simple configurations on other machines (without the routes and using eth0 instead) are behaving like this. Perhaps the hardware details are more interesting here (taken from a different machine which shows the same behavior): The network cards are on-board: root@valinor:~# lspci | grep -i eth 00:08.0 Bridge: nVidia Corporation MCP55 Ethernet (rev a3) 00:09.0 Bridge: nVidia Corporation MCP55 Ethernet (rev a3) It's not a cheap 0815 - hardware, but Supermicro Servermainboard installed. The cards are connected to a Cisco Catalyst 2960G 24 Port Switch with a recent IOS installed. The ports on that Switch are active (neither deactivated , nor in the "yellow" Cisco - State) when the System comes up.
