There are more. There are models where each ISP gets its own customer vlan 
and L2 equipment do inspection of ARP/ND and does security filtering on 
L2/L3 using this information. There are also L3 networks where the traffic 
is source-routed out to the correct ISP, or each ISP gets its own VRF in 
the equipment and it's VRF a long way out.

To the original poster. People using PPPoE for FTTH makes me sad. When 
someone suggests this, please just say "go back to the drawingboard, redo 
it right".
