Mình xem qua traceroute của bạn và bản routing thì nó không hợp lí lắm.
Mặc dầu trong bản routing thì đi qua 192.168.5.2 để tới 192.168.6.6 nhưng traceroute thi lại đi qua 192.168.1.2.

Cho nên cost trong OSPF bạn chỉnh nó về mặc định hết đi.
Cộng với làm như thầy Minh nói nữa có thể OK.

Đúng là mình có chỉnh lại cost, để mình trả về default xem thế nào
Cảm ơn nhiều!

Re: Help

Chào Thầy và các mod

Hiện tại Hiệu đã làm theo cách thầy Minh chỉ nhưng mô hình hiện vẫn chưa chạy! Vẫn bị loop tại lớp DSW, Hiệu làm theo logmeinvietnam bỏ ospf cost đi
Sau đây là bảng route trên các con thầy và các bạn xem cho nào sai thì chỉ dùm

Chào bạn,

B1: Bạn show run SG1-DSW-001 và SG1-DSW-002 cho mình xem.
B2: Trên pc bạn gõ arp -d--> Sau đó bạn tracert 192.168.9.1--> rồi gõ arp -a --->show kết quả arp -a lên cho mình xem thử.

Chào bạn,
Mình lấy file show run của bạn chỉnh sửa. Bây giờ traceroute hết loop rồi, bạn coi theo đó nha.

Chào Tuấn!
Hiệu thấy đâu có khác gì file cấu hình của Hiệu đâu! Tuấn chỉ dùm xem Hiệu sai cho nào với! Theo như Tuấn làm thì chỉnh lại lớp CSW-001 nhưng vấn đề Hiệu gặp phải đang nằm ở lớp DSW mà.
Tuấn chỉ dùm nha!
Àh mà Tuấn cho Hiệu hỏi là sao trên SG1-ASW-001 Hiệu không thấy Tuấn tắt routing đi vậy

Re: Thầy dangquangminh

bạn nên cấu hình đồng bộ các yêu cầu như sau:

- Con SG-DS1-001 là router DR trong mạng OSPF, con kia là BDR.
- Con SG-DS1-001 là active router trong HSRP.
- Con SG-DS1-001 cũng là root primary của spanning tree trên các vlan. Con DSW còn là là root scecondary của spanning tree.

Nghĩa là, bạn cần thiết kế sao cho các Distribution layer switch có vai trò nhất quán cho cả ba giao thức mà bạn sử dụng: OSPF, HSRP và spanning tree.

- Chào thầy Minh
- Cảm ơn thầy đã post bài trả lời cho Hiệu nhưng Hiệu thấy nếu làm như mô hình của thầy nói thì chưa hợp lý vì như thế chưa tối ưu được hệ thống, với lại việc sử dụng lớp CSW với chức năng như thế thì hơi phí tài nguyên phải không thầy
- Thầy bỏ quá cho em nếu em nói sai nha! he he
Chúc VNpro lớn mạnh, và là nơi nếu khó khăn chúng em sẽ tìm tới he he

Re:Cần giúp đỡ vấn đề Routing

Chào các anh em!

Mô hình trên mình đã làm cho nó chạy ổn định rồi, bữa qua mình kiểm tra cấu hình tất cả đều đúng.
Mình chia sẻ cùng anh em kinh nghiệm khi làm mô hình trên

- Nếu đã ping thấy hết các host trong mô hình, sho ip route đều đúng như ý muốn mà traceroute không đươc anh em kiểm tra lại xem máy của mình có nối vào 1 mạng khác nữa không ví dụ PC của Hiệu có 2 card mạng 1 cái nối vô mô hình, 1 cái sd nội bộ, mặc dù hiệu đã add route trên máy tính để nó nói chuyện với mô hình) nhưng khi traceroute nó ngu không biết đi đâu ping thì nó loop hoài, nhưng nếu mình disable card nội bộ đi thì tất cả đều ok (Đây là kinh nghiệm mà Hiệu phải trả giá bằng nửa tháng mới biết đó)

- Để track hoạt động được thì trong bảng routing table phải có ip hoặc host cần track. Nếu không ping vẫn thấy ip đầu kia nhưng sho track vẫn báo là Down

- Khi sử dụng OSPF trong mô hình để hạn chế quảng bá trên route (nên sử dụng route map).

- Chú ý trong quá trình đặt Accesslist và cấu hình VLan để cập nhật đồng bộ trên các thiết bị.

- Khi sử dụng DHCP Snooping nên chú ý các Port Trust

- Access Switch nên bật cả 2 tính năng spanning-tree uplinkfast,spanning-tree backbonefast

- Trong quá trình làm có khó khăn gì anh em post bài cùng nhau giải quyết
Đây là Recommended

Đây là mô hình

Đây là cấu hình HSRP, OSPF, Vlan Trunking anh em nào cần thì sử dụng
