For some very specific reason, I need to create 4 virtual interfaces with different MAC address on each virtual interface, the frames from those interfaces will needs be sent over a single physical interface without any VLAN tags (the device on other ends will look at my PC and thinks my PC is a dumb switch because frames from different MAC address is being sent towards them)
I've tried this command
ip link add link eth0 name untagged type vlan id 0 which managed to create an untagged virtual interface but when I tried to create another one and replace the
0 then it said
RTNETLINK answers: File exists
Again, I'm not trying to create a trunk over the physical interface, a tagged frame being sent out the physical interface is not suitable for my purpose because the other end doesn't understand a VLAN tagged frame or a trunk interface for that matter.
How I could accomplish this?
