Question
OSPFv2 is an IGP running on an IPv4 network. OSPFv3 is an IGP running on an IPv6 network. The basic working mechanism of OSPFv3 is the same as OSPFv2, such as the election of DR and BDR. As shown in the figure, an engineer uses three routers to test IPFv6 services. He wants to realize the interconnection of IPv6 networks by running OSPFv3. Which of the following descriptions about DR election on this network is correct?
Exhibit
Options
- AAfter the network converges, R1 is powered off and restarted. When the network converges again,
- BAfter the network converges, a new device R4 is added to the broadcast link, and the priority of R4
- CAfter the network converges, R1 is the DR.
- DAfter the network converges, the engineer changes the priority of R1 to 100. The priority of R2 is
