• Question 1:

  During the daily troubleshooting process, engineers may need to view some alarm information of the device. Run the terminal command to enable the terminal to display the debugging/log/alarm information sent by the information center.

  monitor

• Question 2:

  OSPF is deployed in a campus to achieve network interworking, and OSPF is also enabled on the GEO/0/2 interface of R3. Area1 is deployed as an NSSA area, and the device addresses are shown in the figure. An engineer configures a static route on R3 to access the loopback interface address of R4, and imports the static route in the 0SPF process. At this point, in the Type5 LSA received by R1, the forwarding address (FA) is____. (Note: Please fill in the IP address without mask)

  

  10.1.23.2

• Question 3:

  All routers in a network run IS-IS, and all are in Area 49.0001, where the L SDB of R1 is shown in the figure According to this, it is judged that the DIS of Level-2 is. (Please fill in the device name, such as R1)

• Question 4:

  IGP converges faster than BGP, which may cause network traffic loss. By enabling the OSPF and BGP linkage feature of the device, the device can keep the OSPF and BGP linkage during the set linkage time.____The router makes the link metric value in the LSA advertised to be the maximum value, so as to inform other OSPF devices not to use this router to forward data, so as to avoid traffic loss.

• Question 6:

  FILL IN THE BLANK

  On the network shown in the figure, OSPF is deployed on R1 and R2. IS-IS is deployed on R2 and R3. To enable R1 to obtain the route to 10.0.3.3/32, ISIS routes are imported into OSPF on R2. In this case, the next hop address to 10.0.3.3/32 in the routing table of R1 is_____.

  

  10.0.23.2

• Question 7:

  Drag and Drop The configuration shown is performed on R2 to filter all incoming routes. Suppose there is a BGP route with the AS_Path attribute of [100200300400] on R1 that needs to be sent to R2. Please help the network administrator to adjust the AS order in the AS_Path attribute of the route on R1 to ensure that the route entry will not be filtered by the routing policy of R2____, ____, ____, ____.
