Topology

Tasks
OSPF is partially configured on all devices. Complete the configurations to achieve these results:
1. Configure R3 so that R20 is always designated as the BDR.
2. Configure R10 so that it does not participate in the DR/BDR election. Do not use the ip ospf network point-to-point command under the interface configuration to accomplish this task.
