A campus has deployed IPv6 for service testing. There are 4 routers (R1, 22, R3 and R4) in this network, running 0SPFV3 to realize the interconnection of IPv6 network. A new router R5 needs to be connected to the network for testing. An engineer introduces a direct route in the OSPFVV3 process of R4 so that devices in the campus network can access the GE0/0/1 port address of R5. Which of the following statements about the scene is true of?

A. R2will generate aType4 LSAonly inArea 0internal flooding

B. R4will generate aType5 LSAdescribe bowIenteredIPv6routing prefix

C. R2will generate aType4 LSAdescribeR4ofRouter ID

D. R4will generate aType5 LSAonly inArea 1internal flooding

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)

A. 10.1.23.2

The IS-IS neighbor relationship between R3 and R1 is not established. According to the information in this figure, what is the possible reason?

A. R3andR1ofIIHAuthentication failed

B. R3andR1ofSystem IDrepeat

C. R3andR1ofI5-LevelMismatch

D. R3andR1the interconnect interfacecircuit-typeMismatchWhen troubleshooting MSTP faults, you executed the display current-configuration command to obtain
