Hi, I'm currently trying to search around and build scheme with QinQ implemented. My question for people already familiar with such "double tagged" frames concept. How It is done in the nutshell, is this 2 tags are originated from access layer switch (The switch were client is connected), or second tag is inserted by the next-hop second network switch that already receives this one-tagged frame.
Not sure that this forum is the right place to ask such questions, but I hope it's not the last one.
Thank you for attention
