Cấu hình ADSL trên Cisco 2600 dùng card ADSL WIC-

[dangquangminh]

Đoạn này bị sai nè:

ppp chap hostname Dsl-inf2
ppp chap password 0 123456
ppp pap sent-username Dsl-inf2 password 0 123456

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?
