4.9 OSPF Configuration Example

4.9.1 Configuring DR Election Based on OSPF Priority

I. Network requirements
Four S3900 switches, Switch A, Switch B, Switch C, and Switch D, which run OSPF,
are on the same segment, as shown in Figure 4-3. Perform proper configurations to
make Switch A and Switch C become DR and BDR respectively. Set the priority of
Switch A to 100 (the highest on the network) so that Switch A is elected as the DR. Set
the priority of Switch C to 2 (the second highest priority) so that Switch C is elected as
the BDR. Set the priority of Switch B to 0 so that Switch B cannot be elected as the DR.
No priority is set for Switch D so it has a default priority of 1.
