DSLAM aggregation – L2 QnQ
Each DSLAM receives a different P-VLAN, ensuring isolation between the equipments
The DSLAM assigns different C-VLAN for each client, ensuring isolation between clients
Using VLAN translate it is possible to match a single P-VLAN+C-VLAN and rewrite fields, allowing a
corporate VPN access connectivity without passing through the BRAS
