A park deployed IPv6 for business testing. There are 4 routers (R1, 22, R3 and R4) in this network, running OSPFv3 to realize the interconnection of IPv6 network. There is a new router R5 that needs to be connected to the network for testing. An engineer introduced a direct route in the OSPFvV3 process of R4 to realize that the devices in the campus network can access the GE0/0/1 port address of R5. Which of the following descriptions of the scene are correct? (Multiple choice)

An enterprise purchased the leased lines of two operators. In order to optimize the route, the enterprise used the 6GP protocol to learn routing entries of the two operators. However, the company found that after such a configuration, the traffic of the export routing increased greatly. After the network engineering investigation, it was found that the traffic of the two operators was passed to each other through the company's export router.


Therefore, the company intends to use routing strategies to prevent the traffic between different operators from passing each other. Is the configuration in the figure correct?
