Configuring OSPF on Router2
Router2 has a high priority to ensure it becomes the BDR for this area, and configures the DSL interface slightly differently—assume this will be a slower connection resulting in the need for longer timers, and a higher cost for this route.
Otherwise it is a standard OSPF configuration.
