Chào các bạn,
Mình có cấu hình 1 Lab như sau:
R0-R1-R2 thuộc EIGRP Autonomous 101 (AS 101)
R1-R3-R4 thuộc EIGRP Autonomous 102 (AS 102)
Sau khi cấu hình các routers xong thì các router trong AS 101 đã kết nối tốt đẹp và routers trong AS 102 cũng đã kết nối được với nhau.
Nhưng router của AS 101 không ping được router trong AS 102.
Vậy tôi phải cấu hình R1 như thế nào để routers của 2 AS systems có thể kết nối được với nhau ?????
Sau đây là config của Router Border R1 :
