Network requirements1) Requirement analysisUse OSPF to realize interconnection between devices in a broadcast network. Deviceswith higher performance should become the DR and BDR to improve networkperformance. Devices with lower performance are forbidden to take part in DB/BDRelection.Based on the customer requirements and networking environment, assign properpriorities to interfaces.2) Network diagramFigure 2-3 shows the network diagram.Device Interface IP address Router ID Interface prioritySwitch A Vlan-int1 196.1.1.1/24 1.1.1.1 100Switch B Vlan-int1 196.1.1.2/24 2.2.2.2 0Switch C Vlan-int1 196.1.1.3/24 3.3.3.3 2Switch D Vlan-int1 196.1.1.4/24 4.4.4.4 1Figure 2-3 Network diagram for OSPF DR selectionII.
