Configuration
Requirements
Use OSPF to enable communication between devices in a broadcast network.
Devices with higher performance should become the DR and BDR to improve
network performance. Disable the devices with lower performance from taking
part in the DR/BDR election.
Based on the customer requirements and networking environment, assign proper
priorities to interfaces.
