What tools can rewrite vlan?

Question

Computer networks

For greater clarity, I drew a diagram of work, the question is how to reproduce vlan mapping / translation or Q-in-Q using Linux tools, without using managed switches, as you can see from the vlan10 and vlan20 diagram, convert to vlan100 and on another server already convert them back, if there are such ready-made tools, tell me where to look, or if it is possible to implement it programmatically, it’s also interesting where to look and where to start, I will be very grateful!

Answer 1
