This is still unclear to me.
How do you split Ethernet packets travelling on a single cable that are
tagged with different vLANs? This can only occur in a Ethernet device
(the Switching Matrixi in my example). I do not see how you do it
otherwise. So your port needs to go to one other Ethernet port (portB in
my example)

The Switching Matrix is the virtual node, you mean?

True:-)
