Load Balancing Leaseline and Megawan ADSL

[tienmv]

Hi All
Minh co mo hinh mang dinh kem:
- Tren Router A minh cau hinh nhu sau:
* Router OSPF 1
Resdistribute Static
Network 172.16.1.0 0.0.0.3 are 0
Network 10.x.x.x 0.0.0.255 are 0
* IP Route 192.168.x.x 255.255.255.0 10.10.1.x(Next hop BRAS buu dien chay Megawan)
* IP Route 172.16.128.x 255.255.255.0 10.10.1.x(Next hop BRAS buu dien chay Megawan)
* Config Policy Base Routing
- Tren Router B cau hinh OSPF, EIGRP
- Tren Switch cau hinh EIGRP va Static de Routing Megawan ADSL ( IP route 10.x.x.x 255.255.255.0 172.16.129.253)

Neu ca ADSL va Leaseline deu Active thi tu may 192.168.x.x khong ping thay lop mang o Router A. Nhung neu shutdown 1 trong 2 cong cua Router A thi chay binh thuong hoac them distance metric static route thi no se uu tien chay Leaseline. Nhu vay chi co the cau hinh lam backup duoc khong chay duoc song song cung luc hai duong.
Cac ban co giai phap nao giup minh voi
Thanks

Cac ban co' the chi giup minh mot cach nao de can bang tai hay su dung toi uu hai duong truyen nay ko.

Hi,
Trong trường hợp các bạn muốn load balancing thì tốt nhất là nên tạo ra một tunnel. Việc tạo Tunnel này sẽ làm cho hai Router đẫu cuối sẽ thấy mạng MegAWAN là trong suốt, khi đó việc định tuyến sẽ chỉ thực hiện qua các tunnel này thôi.
Cái này mình đã thử và thấy là tương đối tốt.
Chúc thành công.
