on the switch. Inside the ISP network, the packet is broadcast along the port of VLAN
10 until it reaches the switch B.
3. Switch B finds out that the port connected to user network 2 is a customer port. Thus, it
removes the outer tag in compliance with the conventional 802.1Q protocol to recover
the original packet and sends the packet to user network 2.
4. In this way, data between user network 1 and user network 2 can be transmitted
transparently. The VLAN ID of the user network can be planned regardless of the
conflict with the VLAN ID in the ISP network.
