The Router ID is not required to bethe router’s IP address. Dell Force10 recommends using the IP address as the Router ID for easiermanagement and troubleshooting.Use the no router ospf process-id command syntax in the CONFIGURATION mode to disable OSPF.Use the clear ip ospf process-id command syntax in EXEC Privilege mode to reset the OSPFv2 process.Assign an OSPFv2 areaAfter OSPFv2 is enabled, assign the interface to an OSPF area. Set up OSPFAreas and enable OSPFv2 onan interface with the network command.You must have at least one AS area: Area 0. This is the Backbone Area. If your OSPF network containsmore than one area, you must also configure a backbone area (Area ID 0.0.0.0). Any area besides Area 0can have any number ID assigned to it.The OSPFv2 process evaluates the network commands in the order they are configured. Assign thenetwork address that is most explicit first to include all subnets of that address. For example, if you assignthe network address 10.0.0.0 /8, you cannot assign the network address 10.1.0.0 /16 since it is alreadyincluded in the first network address.When configuring the network command, you must configure a network address and mask that is asuperset of the IP subnet configured on the Layer-3 interface to be used for OSPFv2.Use this command in CONFIGURATION ROUTER OSPF mode to set up each neighbor and OSPF area.The Area can be assigned by a number or with an IP interface address.Command Syntax Command Mode Usagerouter-id ip address CONFIG-ROUTER-OSPF-idAssign the Router ID for the OSPFv2process.IP Address: A.B.C.DCommand Syntax Command Mode Usagenetwork ip-address mask area area-id CONFIG-ROUTER-OSPF-id Enable OSPFv2 on an interface andassign an network address range to aspecific OSPF area.IP Address Format: A.B.C.D/MArea ID Range: 0-65535 or A.B.C.D/M
