Network requirements
• Configure router priority 100 for Switch A, the highest priority on the network, so it will become the
DR.
• Configure router priority 2 for Switch C, the second highest priority on the network, so it will
become the BDR.
• Configure router priority 0 for Switch B, so it cannot become a DR or BDR.
• Switch D uses the default router priority 1.
