Documentation Roadmap Stage 1: Using the Switch for the First Time Stage 2: Gaining Familiarity with Basic Switch Functions Stage 3: Integrating the Switch Into a Network Anytime Related Documentation Page User Manual CD Technical Support Page 1 Configuring OSPF OSPF Specifications OSPF Defaults Table Enables OSPF. Enables an interface. Sets the overflow interval value. OSPF Quick Steps Page 11You can display OSPF area settings using the show ip ospf area command. For example: 12You can display OSPF interface settings using the show ip ospf interface command. For example: OSPF Overview OSPF Areas Classification of Routers Virtual Links Stub Areas Not-So-Stubby-Areas Totally Stubby Areas Equal Cost Multi-Path (ECMP) Routing Non Broadcast OSPF Routing Graceful Restart on Stacks with Redundant Switches Graceful Restart on Switches with Redundant CMMs Configuring OSPF Preparing the Network for OSPF Activating OSPF Enabling OSPF Removing OSPF from Memory Creating an OSPF Area Creating an Area Specifying an Area Type Enabling and Disabling Summarization Displaying Area Status Deleting an Area Configuring Stub Area Default Metrics Setting Area Ranges Configuring a Totally Stubby Area Creating OSPF Interfaces Creating an Interface Assigning an Interface to an Area Activating an Interface Interface Authentication Modifying Interface Parameters Creating Virtual Links belonging to this interface.
