The public network tunnel between PE1 and PE2 has been established (the label information is shown in the figure), and PF1 has
The 192.168.1.0/24 network segment route is advertised to PE2 through the MP.JIBGP neighbor relationship, and the route learning is normal. When grabbing between P and PE1, when Site2 accesses the 192.168.1.0/24 data of Sitel, the outermost label
What should the sign be?
FEC In/Out label

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.
As shown in the figure, OSPF is enabled on all interfaces of the router, and the ip address identified in the figure is the device's IP address.
Loopback0 presses the IP address of the port, RI, R2, R3EJLoopbacD is advertised in the area 1, R4
LoopbacfkD advertises in area D and which of the following functional addresses can be pinged between the LoopbackD announcements of R5 and R5 in area 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)
You have set IS-IS IPv6 enable under the interface, what is the meaning of this command?
As shown in the figure, on the R1 router, network administrator A sends the routing entry to R2 through the routing policy
After modifying the MED value, you can control the path of traffic entering the AS100
As shown in the figure, the operator's BGP/MPLS IP VPN backbone network builds SP through DP. If you want to implement user X
If the two sites communicate through the BGP/MPLS IPVPN network, PE1 and PE2 must use a 32-bit masked loopback interface address to establish an MP-IBGP peer relationship.
From this picture, we can judge

When a fault occurs, the fault can be classified to reduce the scope of fault location. Which of the following is not an interface configuration fault?
Which of the following reasons may cause the hosts in the same VLAN of the LAN to fail to communicate with each other?
Which of the following is not part of the preparatory work for the cutover plan?
IS-IS is a link-state routing protocol that uses the SPF algorithm for route calculation. As shown in the figure, a campus deploys both IPv4 and IPv6 and runs IS-IS to achieve network interconnection. R2 only supports IPv4. Which of the following statements is true about the topology calculation of this network?
As shown in the figure, OSPF is deployed in a campus, and Area 1 is deployed as an NSSA area. In the case of missing header, R2 will automatically generate a missing header route of Type 7 LSA and flood it in the NSSA area
If faced with a complex network failure, and it is estimated that the troubleshooting cannot be completed in a short period of time, and the user urgently needs to restore the availability of the network, then the correct approach is.
As shown in the figure, all interfaces of the router enable DSPF. The cost value of the link is marked in the figure. R2
The LoopbackD interface is advertised in area 1, then the cost of R1 reaching 10.2/32 is?
In OSPF, the A, BR will convert all type 7 L SAs in the NSSA area to type 5 L SAs.
After the cutover acceptance is completeD. what work still needs to be performed in the closing stage?
A router runs OSPF, and the output information is shown in the figure. Which of the following statements is correct?

A network engineer entered the following information when troubleshooting OSPF faults. Based on this, you can judge what causes the adjacency relationship to fail to be established normally?
The OSPF protocol is run between CE and PE, when CE1 advertises the route of its site to CE2. Which of the following descriptions is incorrect?
Assuming that the neighbor relationship between BGP routers has been established successfully, the configuration on R1 is shown in the figure. ask for R1
