Cấu hình ADSL trên Cisco 2600 dùng card ADSL WIC-

[dangquangminh]

Xin chào,

Cấu hình ADSL cho Cisco 2620 dùng card WAN-ADSL cho mạng ADSL tại Việt Nam. Cấu hình dưới đây là một working configs.

Trong cấu hình này, chú ý cách dùng load-balancing trên leased-line và đường ADSL dùng policy-routing. Ngoài ra, chú ý cách gán MAC address của FE cho interface ATM. Cool tips!

Các bạn có thể tham khảo cấu hình này khi triển khai mạng ADSL tại Việt Nam.

Chúc các bạn thành công,
Minh

Chào anh! Em không hiểu vấn đề cấu hình ADSL tai sao lai liên quan đến ATM.

[ntemt]

Vì do tính chất của ADSL thôi mà. Nó sử dụng ATM làm môi trường truyền dẫn từ DSLAM đến ISP

[blackman]

Chào Tâm! Vậy em có biết hiện nay ở VIỆT NAM ISP nào không sử dụng ATM cho kết nối DSLAM tới ISP ko. Và Vpc sao lại là 0/33

[luumanh_lichsu]

ATM thường được dùng từ tổng đài DSLAM đến ISP vì dễ dàng triễn khai QOS (dv mới đây của VNN cam kết tốc độ Maxium va Minimum trên ADSL từ 1/7/2005)

các bạn ơi, mình muốn cấu hình VPN trên Wic-1ADSL cho Router 1760, nhưng em không biết IOS nào hỗ trợ hai tính năng trên, đã ai cấu hình như thế chưa, cho mình xin IOS của nó nhé, Thanhks

[trannam]

cho em hỏi mô hình của bài lab này là thế nào? Có cần phải có thiêt bị gì để làm DSLAM ko? Hay là PPPoE Client nối trực tiếp vào PPPoE Server? Nếu vậy thì cắm dây thế nào?

Nếu như router của em ko có Wic-ADSL, em phải chuyển modem ADSL thành mode nào để có thể config PPPoE Client trên router?

Thanks

Dear Mr. Minh,

Mình làm theo bài này thì khi tới lệnh int ATM, nó báo lỗi, vậy con router của mình ko support ADSL hả ?

[dangquangminh]

Router đang dùng là router gì? Đang gắn modem vào cổng Ethernet phải không?

[soibien]

mình đang dùng router 1800, đúng vậy, modem gắn vào cổng f0/1 của router, còn cổng f0/0 gắn vào Lan.

Thầy cho em xin hỏi 1 chút . Em dùng router Cisco 2621 dùng 2 wic-adsl , 1 line VNN và 1 line Viettel . Trong hệ thống có 1 DNS server IP : 192.168.210.200 , các máy client có thể truy vấn DNS được bằng lênh "nslookup". Hiện tại trong DNS em đang forwarders : DNS của VNN và Viettel + 4.2.2.2 . Trên máy Server thì dùng web ra Internet được nhưng rất chậm , còn các máy client trong 3 VLAN thi phân giải tên miền được nhưng không dùng web ra Internet được (ping các địa chì ngoài Internet vẫn reply) .Đây là file cấu hình Router :

Em đang dùng line VNN ra ngoài là chính chưa cấu hình load balancing , nhưng đã gặp trục trặc , mong thầy và các bạn hướng dẫn khắc phục lỗi trên , chân thành cảm ơn.

[dangquangminh]

Router chạy chậm là do chưa cấu hình load balancing. Bạn cấu hình phan routing cho nó load balacing thì nó chạy nhanh thôi.

Biết cách cấu hình load balancing chưa?
