BFD Bidirectional forwarding detection (BFD) provides a single mechanism to quickly detect and monitor the connectivity of links between OSPF neighbors, reducing network convergence time. For more information about BFD, see High Availability Configuration Guide. Protocols and standards • RFC 1765, OSPF Database Overflow • RFC 2328, OSPF Version 2 • RFC 3101, OSPF Not-So-Stubby Area (NSSA) Option • RFC 3137, OSPF Stub Router Advertisement • RFC 3630, Traffic Engineering Extensions to OSPF Version 2 • RFC 4811, OSPF Out-of-Band LSDB Resynchronization • RFC 4812, OSPF Restart Signaling • RFC 4813, OSPF Link-Local Signaling OSPF configuration task list Make a proper plan before configuring OSPF. To run OSPF in a routing domain, you must first enable OSPF on the routers. Then use the default settings of parameters such as the hello interval, LSA delay timer, and SPF calculation interval. You can also configure them as needed. OSPF routers should be configured on an area basis. Wrong configurations may cause communication failures, routing information blocks, and routing loops. Complete the following tasks to configure OSPF: Task Enabling OSPF Configuring OSPF areas Configuring OSPF network types Configuring OSPF route control Configuring a stub area Configuring an NSSA area Configuring a virtual link Configuring the broadcast network type for an interface Configuring the NBMA network type for an interface Configuring the P2MP network type for an interface Configuring the P2P network type for an interface Configuring OSPF route summarization Configuring OSPF inbound route filtering Configuring ABR Type-3 LSA filtering Configuring an OSPF cost for an interface Configuring the maximum number of OSPF routes Configuring the maximum number of ECMP routes Configuring OSPF preference Remarks Required Optional Optional Optional Optional Optional Optional Optional Optional Optional Optional Optional Optional 65
