clear ip ospf graceful-restart { vrf vrf-name | all-vrf }

clear ip ospf counters { all | ethernet slot/port | loopback number | port-channel number | ve vlan-id } [ vrf vrf-name ]

clear ip ospf neighbor { ip-addr | all } [ vrf vrf-name ]

clear ip ospf routes { ip-addr/mask | all } [ vrf vrf-name ]

all

counters

all: Clears all counters.
ethernet slot / port: Specifies an Ethernet slot and port.
loopback number: Specifies a loopback interface. Valid values range from 1 through 255.
port-channel number: Specifies a port-channel.
ve vlan-id: Specifies a virtual Ethernet (VE) interface. Valid values range from 1 through 4096.
