Network requirements
Four Switch 8800 Family series, Switch A, Switch B, Switch C and Switch D, which
can perform the router functions and run OSPF, are located on the same segment,
as shown in the following figure.
Configure Switch A and Switch C as DR and BDR respectively. The priority of
Switch A is 100, which is the highest on the network, so it is elected as the DR.
Switch C has the second highest priority, that is, 2, so it is elected as the BDR. The
priority of Switch B is 0, which means that it cannot be elected as the DR. Switch D
does not have a priority, which takes 1 by default.
