Frame Relay Full Mesh

[luancb]

Cấu hình Frame Relay Point to point, dạng full-mesh. R2 và R3 có kết nối trực tiếp, chứ không thông qua R1 như mô hình dạng Hub&Spoke .
Chạy định tuyến RIP để quảng bá mạng cho nhau và mạng hội tụ, tất cả IP ping thấy nhau .

Mình cũng cấu hình y như bài của bạn nhưng không biết tại sao lại không chạy? Mình làm trên GNS3 với con c7200 và dùng ISO c7200-jk9o3s-mz.124-12.bin. Có khi nào là do GNS3 hay do cái ISO không bạn?

[luancb]

Bạn show run các router lên để xem thử, chắc có vấn đề gì đó, mà bạn chưa tìm ra.

[natostr]

cảm ơn bạn nhiều. Mình đã làm được rồi. Cũng không biết là sai ở đâu (hay do cái ISO):106:, sửa hoài mệt quá@-) nên mình quyết định làm lại từ đầu với 1 ISO khác[-o< và cuối cùng là thành công=D>. Cảm ơn bài viết của bạn :113:

[luancb]

Nhiều khi do cấu hình, cũng hơi phức tạp, có thể gõ sai gì đó mà nhìn hoài ko ra. nên... ^_^.

[longnguyen2512]

tương tự vậy

sau vài giây thì delete ko hiue63 vì sao?

[luancb]

Bạn show run lên thử xem ?!

[longnguyen2512]

Chào bác luancb !
bác cho e hỏi nếu 3 mạng loopblack e dùng 3 định tuyến khác nhau thì sao nhỉ?
làm sao để chúng thấy nhau!
Hình như theo lý thuyết thì qua frame-relay là ko được hả bác?
mạng 1.1.1.0/24 dùng rip
mạng 2.2.2.0/24 dùng eigrp 100
mạng 3.3.3.0/24 dùng ospf 200
thì sao bác nhỉ?

[luancb]

Chạy định tuyến khác nhau, bạn phải sử dụng công cụ Redistribute để cho các mạng thấy nhau.

[longnguyen2512]

cụ thể là e làm cái bài này

tù hn ko ping được tới vùng eigrp của hcm
và từ ct củng ko ping tới hn được chỉ ping tới hp được àh

[longnguyen2512]

vậy làm sao để cho hn thấy các route khác(ct,hcm,bl) nhỉ?
bác cho e biết e bị sai chỗ nào nhỉ?
làm hoài ko ra

[dangquangminh]

RIP version 1 có tối đa 16 hop counts. Bạn Redistribute từ OSPF vào RIP mà dùng default metric lên đến 100 thì các route do OSPF đưa qua sẽ xem như "unreachable". Chỉnh lại default metric bằng 3 (<16) là được.

[longnguyen2512]

thank bác! e làm oki rồi!
