Configuring OSPFv3 DR
Election
Network requirements
In the following figure:
■ 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.
■ RouterD has the default priority 1.
