I am not completely sure about the PPPoE model you have as you mention 2 different things: - L2TP - VPLS
If you get a L2 circuit (VPLS) with no IP configured on it, and you terminate PPPoE sessions on your router, then this is not L2TP, but regular PPPoE. PPPoE is a L2 protocol which runs directly over Ethernet and does not require an IP layer (the customer does not get an IP address before the PPP layer assigns it). With L2TP you would have an IP based tunnel from the SP, while they terminate the PPPoE session, and they would tunnel it to your LNS. In that case the LAC (SP BRAS) has to have IP connectivity to your LNS device.
