RE: Bài viết FR with Tunnel

Nếu có hai router 2500 mỗi router có 2 cổng serials, có thể kết hợp với nhau để làm một FrameRelay Switch có 4 cổng serials. Hai router sẽ nối với nhau qua cổng Ethernet, sau đó tạo một tunnel trên kết nối Ethernet này.

Cấu hình chi tiết như sau:

FRSwitch 2:

sh run

frame-relay intf-type dce
frame-relay route 104 interface Tunnel0 104

Cần chú ý cách dùng lệnh frame-relay route trên các framerelay switch.
