Configuring OSPFv3 DR election
Network requirements
As shown in Figure 107:
• The priority of Switch A is 100, the highest priority on the network, so it will be the DR.
• The priority of Switch C is 2, the second highest priority on the network, so it will be the BDR.
• The priority of Switch B is 0, so it cannot become the DR.
• Router D has the default priority 1.
