Open Shortest Path First (OSPFv2 and OSPFv3) | 7052. Enable OSPF globally. Assign network area and neighbors.3. Add interfaces or configure other attributes.The following configuration steps include two mandatory steps and several optional ones:• Enable OSPFv2 (mandatory)• Enable Multi-Process OSPF• Assign an OSPFv2 area (mandatory)• Enable OSPFv2 on interfaces• Configure stub areas• Configure OSPF Stub-Router Advertisement• Enable passive interfaces• Enable fast-convergence• Change OSPFv2 parameters on interfaces• Enable OSPFv2 authentication• Enable OSPFv2 graceful restart• Configure virtual links• Redistribute routes• Troubleshooting OSPFv2For a complete listing of all commands related to OSPFv2, refer to the OSPF section in the FTOSCommand Line Interface document.Enable OSPFv2Assign an IP address to an interface (physical or Loopback) to enable Layer 3 routing. By default OSPF,like all routing protocols, is disabled.You must configure at least one interface for Layer 3 before enabling OSPFv2 globally.If implementing, Multi-Process OSPF, you must create an equal number of Layer 3 enabled interfaces andOSPF Process IDs. For example, if you create 4 OSPFv2 process IDs, you must have 4 interfaces withLayer 3 enabled.Use these commands on one of the interfaces to enable OSPFv2 routing.Step Command Syntax Command Mode Usage1 ip address ip-address mask CONFIG-INTERFACE Assign an IP address to an interface.Format: A.B.C.D/MIf using a Loopback interface, refer to Loopback Interfaces onpage 427.2 no shutdown CONFIG-INTERFACE Enable the interface.
