Refer to the exhibit. Suppose that routers B, C, and D have a default priority, and router A has a priority 0. Which conclusion can be drawn from the DR/BDR election process?
- Router A will become the DR and router D will become the BDR.
- If the DR fails, the new DR will be router B.
- If a new router with a higher priority is added to this network, it will become the DR.
- If the priority of router C is changed to 255, then it will become the DR.
Answers Explanation & Hints:
If the priority is set to 0, the router is not capable of becoming the DR, so router A cannot be the DR. OSPF DR and BDR elections are not preemptive. If a new router with a higher priority or higher router ID is added to the network after the DR and BDR election, the newly added router does not take over the DR or the BDR role.
