ISP ABC provides ADSL service to subscribers using IP addresses between 205.1.1.2-205.1.1.100. Subscribers use PPPoE authentication with PAP. The ISP uses DHCP to assign IP addresses to subscribers and NAT-overload to allow subscribers on the same LAN to access the internet.

ADSL-LAB ISP ABC triềnkhai 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 Cấu hình hệ thống ISP1: ISP1#sh run Building configuration...
