OSPFV2 is an IGP running on an IPv4 network; OSPFV3 is an IGPo running on an IPv6 network. The basic working mechanism of OSPFv3 is the same as that of OSPFV2, such as the election of DR and B, DR. As shown in the figure, an engineer uses 3 routers to test IPv6 services. He wants to realize the interconnection of IPv6 networks by running OSPFV3.
Pass. Which of the following statements about the election of the network DR is correct?

After the network converges, engineers modifyR1the priority is100,R2the priority
is10,R3Keep the default value. When the network converges again,R1forDR, R2forB, DR
After the network converges, a new device is added to the broadcast linkR4,R4the priority is150. When the network converges again,R4forDR
After the network convergesR1Power off and restart, when the network converges again,R3forDR
After the network converges,R1forDR
