I work in an ISP multiple times i have encounter that other ISPs wants to run his customer through my network and they share the VLAN ID that i can't allow for them because it has been used by my network. i want to ask if there is any possibility to use the same Vlan for both ISP.

Hello,
QinQ would be an option, as it would allow you to transport customer VLANs through your network. What specific topology would you need to apply this to ?
IEEE 802.1Q Tunneling (QinQ) and L2PT on L2
