OSPFv3 DR election configuration example
Network requirements
• Configure router priority 100 for Router A, the highest priority on the network, so it will become the
DR.
• Configure router priority 2 for Router C, the second highest priority on the network, so it will become
the BDR.
• Configure router priority 0 for Router B, so it cannot become a DR or BDR.
• Router D uses the default router priority 1.
