4.6.1 Configuring OSPF
 
Lab Activity
  In this lab, you configure OSPF on three Cisco routers. First, you configure loopback interfaces to provide stable OSPF Router IDs. Then you configure the OSPF process and enable OSPF on the appropriate interfaces. After OSPF is enabled, you tune the update timers and configure authentication.
