Hello moi nguoi!
Minh doc qua quyen Cisco Press, Ccie (Exam 350-001) Routing And Switching Official Exam Certification Guide (2006), 2Ed va thay co cho viet ki` ki`.
Kg biet la mi`nh sai hay la` sach no sai , xin moi nguoi cho i kien:
BGP considers each decision step independently. If a step determines the best route for an NLRI, BGP does not bother with the remaining steps. For example, imagine that R1 has five routes to 9.0.0.0/10, two with AS_PATH length 3 and the others with AS_PATH length 5. The decision process
did not determine a best route before reaching Step 4 (AS_PATH length). Step 4’s logic can determine that two routes are better than the others because they have a shorter AS_PATH length. However, because this step does not produce the single winner, the process moves on to the next step,
and " all five routes are still considered " as candidates to be the best route. Each step either produces a winner or moves on to the next step, examining all routes to that NLRI at the next step.
Theo nhu mi`nh test thi` kg giong nhu vay, ca'c step sau ke^' thu`a ket qua cua step truoc.
