OSPF Configuration Examples
Configuring DR/BDR Election
Network requirements
Use OSPF to realize interconnection between devices in a broadcast network. Devices with higher
performance should become the DR and BDR to improve network performance. Devices with lower
performance are forbidden to take part in DB/BDR election.
Based on the customer requirements and networking environment, assign proper priorities to
interfaces.
