If there are 2 different clients that are using the same VLANs in their networks (lets say VLANs 2, 3, 4) and these VLANs are to be transported over a service provider's network. If using QinQ you would need to have 2 seperate VLANs on the SP network to transport the VLANs so that the switches do not get confused about where the traffic is to go. Is there any other solution to this scenario?

not really, L2VPN is more like a tunnels. The L2 traffic is ecapsulated in IP packet and routed (or MPLS switched) to other side as a normal IP packet. You could if you want to put both sides in a separate VRF.
VPLS is a L2 tunnel as well but it works over MPLS, if I correctly remember.

L2VPN/VPLS.
Thanks.

So the clients will be separated by the VFI much like the use of VRF in MPLSVPN?
