A campus network is connected through Huawei S series switches. The administrator has enabled the MAC drift detection function in the network. Which of the following descriptions of this function is wrong?

In the OSPFv3 network shown in the figure, OSPFv3 is enabled on the interconnected ports of R1, R2, and R3, and all are configured with IPv6 global unicast addresses. Then R1, R2, and R3 will all generate Intra-Area-Prefix-LSA.

As shown in the figure, RIR4 is one of the four routers in AS 123. They all run OSPE and realize the routing interconnection within the AS. Among them, the two network segments 10.1.1.0/24 and 10.4.4.0/24 are not published to OSPF. Now, R1 and R4 have established an IBGP peer relationship based on the Loopback0 interface, and published the network segments 10.1.1.0/24 and 10.4.4.0/24 to BGP respectively.

Which of the following methods can enable PC1 and PC2 to communicate with each other?
(Multiple choice)

In the OSPF network shown in the figure, area 1 is an NSSA area, area 2 is a common area, and R4 imports external route 10.0.4.4/32. The Router ID of each device is 10.0.0.X, where X is the device number.

The "asbr-summary 10.0.4.0 255.255.255.0" command is configured in the OSPF processes of R1 and R3. Which of the following routers have routing entries for 10.0.4.0/24 in their routing tables? (Multiple choice)

The Link-LSA generated by an OSPFv3 router is shown in the figure. Which of the following is the number of global unicast addresses configured on the interface?
