Configuring OSPF on Router1
Router1 has a very high priority to ensure it becomes the DR for this area. Also Router1 has the lowest IP address to help ensure it will win in case there is a tie at some point. Otherwise it is a standard OSPF configuration. Setting the priority can only be done in the CLI, and it is for a specific OSPF interface.
