During an attempt to log in to a NetEngine AR6120 through the console port, the network engineer finds that the password is incorrect and the login fails. If a Telnet account can be used to log in to the device and the account has the permission to change the console port password, the network engineer can log in to the device through Telnet to change the console port password.

On the network shown in the figure, IS-IS runs on R1, R2, R4, and R5, and the area ID is 49.0001. IS-IS runs on R3 and R6, and the area ID is 49.0002. The import-route isis level-2 into level-1 command is configured on R2 and R5. In AS 65000, R1, R3, R4, and R6 each establish IBGP peer relationships with R2 and R5. R2 and R5 are RRs, and R1, R4, R3, and R6 are clients. The IBGP peer relationships are established using Loopback0. The IP address of Loopback0 on each router is 10.0.X.X/32, and the router ID is 10.0.X.X, where X is the number of the router. R1 and R4 import the external route 192.168.1.0/24 to BGP through the import- route command, and R3 and R6 import the external route 192.168.2.0/24 to BGP through the import-route command. Which of the following statements are true?

On the network shown in the figure, R1 and R2 use directly connected interfaces to establish a BGP peer relationship. The debugging information shown in the figure is displayed on R2. Drag the values on the left to the corresponding descriptions on the right.

정답:
Explanation:
# Debug Logs on R2:
nginx
CopyEdit
Received OPEN from 10.0.1.1...
Router ID: 10.0.1.1, AS: 100
Received OPEN from 10.0.2.2...
Router ID: 10.0.2.2, AS: 200
* The OPEN message exchanged during BGP neighbor establishment contains:
* Router ID of the peer
* AS number
* Hold time
* Capabilities
From the logs:
* R2 received R1's OPEN message with:
* Router ID = 10.0.1.1
* AS = 100
* R2 ' s own OPEN message shows:
* Router ID = 10.0.2.2
* AS = 200
This gives us the exact matching required.
Official Huawei Extract:
" In BGP, the OPEN message contains the router ID and AS number of the sender. These values are exchanged during session establishment and are visible via debugging logs or display bgp peer outputs. "
