Junos Operating System Highlights SSFJUN01-I © Juniper Networks, Inc. 101 To ensure correct routing knowledge and connectivity, OSPF maintains a special area called the backbone area. OSPF designates the backbone area as Area 0.0.0.0. All other OSPF areas must connect themselves to the backbone for connectivity. All data traffic between OSPF areas must transit the backbone.
