問題3
You are asked to troubleshoot a problem with MSTP and determine why Switch-1 and Switch-2 think they are the root bridge for the same MSTI instances. Switch-1 should be the root bridge for the MSTI 1 instance and Switch-2 should be the root bridge for the MSTI 2 instance. Referring to the exhibit, what is causing this problem?
正確答案: A

Click the Exhibit button.
You are sending traffic to the ge-0/0/0 interface on R1 with the expedited forwarding (101) IP precedence bits. However, the counters on the router show that it is not processing any traffic in the expedited forwarding queue.
