ADSL-LAB



ISP ABC triền khai hệ thống cung cấp dịch vụ ADSL cho các thuê bao, địa chỉ cung cấp xuống các thuê bao sẽ nằm trong phạm vi 205.1.1.2 đếm 205.1.1.100, sử dụng công nghệ PPPoE và xác thực người dùng dùng PAP.
Các thuê bao đầu cuối sẽ dùng DHCP để cấp cho người dùng của mình, đồng thời thực hiện cơ chế NAT – overload để mọi người trong LAN có thể đi được ra Internet
