To ensure security, authentication can be configured in the OSPFv3 process area view.
- A. FALSE
- B. TRUE
Answer: B
NEW QUESTION # 37
Which of the following statement is wrong?
- A. The principle to be followed for manual label allocation is: the value of the outgoing label of the upstream node is the value of the incoming label of the downstream node
- B. LSPs established by statically assigning labels can also be dynamically adjusted according to changes in the network topology, without administrator intervention
- C. Dynamic LSP is dynamically established through label distribution protocols, such as MP-BGP, RSVP-TE, LDP
- D. LSP is divided into static LSP and dynamic LSP. The static LSP is manually configured by the administrator, and the dynamic LSP is dynamically established using the label protocol
Answer: B

NEW QUESTION # 41
An engineer uses two routers to test IPv6 services, and runs 0SPFv3 to implement IPv6 network interconnection. R1 is required to be able to access the loopback interface address of R2.

- A. FALSE
- B. TRUE
Answer: B
NEW QUESTION # 46
IEIF has extended the functions of OSPF by taking advantage of the strong scalability of OSPF. To enable it to support IPv6 networks, the expanded protocol is called OSPFv3, and OSPFv3 is compatible with OSPFv2.

Answer: A
NEW QUESTION # 47
As shown in the figure, the entire network of a certain company uses OSPF to get through the network. However, RouterS and RouterE cannot establish an OSPF neighbor relationship. When detecting OSPF failures, network administrators can execute the display ospf 100 () interface GEO/0/1 command on RouterS to obtain error-related information. Users can perform OSPF failure diagnosis based on this information. (Please use English lowercase letters to complete the command, and the command cannot be abbreviated)
