configuring same vlans customers on m2f router

@manishah hello,
same VLAN customers? did you mean multi customers with VLAN overlap? And the router works as an L2 device, I think QinQ could meet your requirements.

Hope to help you!

yes you are right. there is overlaping of same vlan . what shoud i do ? how do we seperate it.?

As I suggested, since you don't provide the detailed application scenario, I think you can use QinQ.
For example, two customers connected to the device in different interfaces, both of them are using vlan 10. You can use the qinq to seperate them. QinQ will encapsulte the vlan packets with another vlan tag header, outside of the current vlan tag header. The outside vlan tag will helps the device to recognize the different packets though they might have the same inner vlan tag.
