There are, typically, three topology models for modern FTTH (wireline, really) networks that a service provider could deploy:1. SVLAN N:1 model 2. CVLAN 1:1 model 3. Hybrid of both
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".
