Configuring OSPF and OSPFv3 991Configuring OSPF Interface SettingsBeginning in Privileged EXEC mode, use the following commands toconfigure per-interface OSPF settings.Command Purposeconfigure Enter global configuration mode.interface vlanvlan-id Enter Interface Configuration mode for the specifiedVLAN.ip ospf areaarea-id[secondaries none]Enables OSPFv2 on the interface and sets the area ID ofan interface. This command supersedes the effects ofnetwork area command.Thearea-id variable is the ID of the area (Range: IPaddress or decimal from 0 –4294967295)Use the secondaries none keyword to prevent the interfacefrom advertising its secondary addresses into the OSPFv2domain.ip ospf prioritynumber-valueSet the OSPF priority for the interface. Thenumber-valuevariable specifies the priority of an interface (Range: 0 to255).The default priority is 1, which is the highest routerpriority. A value of 0 indicates that the router is noteligible to become the designated router on this network.ip ospf retransmit-intervalsecondsSet the OSPF retransmit interval for the interface.Theseconds variable is the number of seconds betweenlink-state advertisements for adjacencies belonging to thisrouter interface.This value is also used when retransmitting databasedescriptions and link-state request packets. Valid valuesrange from 0 to 3600 seconds (1 hour).ip ospf hello-intervalsecondsSet the OSPF hello interval for the interface. Thisparameter must be the same for all routers attached to anetwork.Theseconds variable indicates the number of seconds towait before sending Hello packets from the interface.(Range: 1–65535).
