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".
