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.
The engineer checked the OSPFv3 routing table entry of R1, as shown in the figure, and found that there was no route to the loopback interface address of R2. Which of the following reasons could not be the cause?
