and Switch B becomes BDR now.

If all Ethernet Switches on the network are removed from and then added to the network again, Switch

B will be elected as the DR (with a priority of 200), and Switch A will be the BDR (with a priority of 100).

Network requirements

Devices in the network run OSPF to realize interconnection. The network is split into three areas: one

backbone area and two non-backbone areas (Area 1 and Area 2). Area 2 has no direct connection to

the backbone, and it has to reach the backbone through Area 1. The customer hopes that Area 2 can

interconnect with other two areas.

Based on the customer requirements and networking environment, use a virtual link to connect Area 2

to the backbone area.
