4.14.4 Example for Configuring DR Election of an OSPF Process
Networking Requirements
As shown in Figure 4-8, Switch A has the highest priority of 100 in the network and is selected
as DR. Switch C has the second highest priority, and is selected as BDR. The priority of Switch
B is 0, so Switch B cannot be selected as DR. The priority of Switch D is not configured and its
default value is 1.
