Clear OSPF Neighbor
Clear OSPF neighbor state information.
Syntax:
clear ospf neighbor <options>
| Option | Description |
|---|---|
- |
Without any option, the command clears all the OSPF neighbors. |
instance <instance-name> |
Clears OSPF neighbor information for the specified instance. |
instance <instance-name> <afi> |
Clears OSPF neighbor for the specified address family. Supported AFI values are 'ipv4' and 'ipv6'. Supported AFI values are 'ipv4' and 'ipv6'. When using an IPv6 address family with OSPFv3, an instance ID ranging from 0 to 31 must be specified. |
instance <instance-name> <afi> area <area-id> |
Clears OSPF neighbor for the specified area of the specified instance and address family. |
instance <instance-name> <afi> area <area-id> interface <interface-name> |
Clears OSPF neighbor for the specified interface for the specified area and address family of the specified instance. |
force |
Forcefully clears all the OSPF neighbors. This may impact DR/BDR election. |
force instance <instance-name> |
Forcefully clears the neighbor for the specified instance. |
force instance <instance-name> <afi> |
Forcefully clears OSPF neighbor for the specified address family. |
force instance <instance-name> <afi> area <area-id> |
Forcefully clears OSPF neighbor for the specified area of the specified instance and address family. |
force instance <instance-name> <afi> area <area-id> interface <interface-name> |
Forcefully clears OSPF neighbor for a specific interface and area of the specified instance and address family. |
Example:
supervisor@rtbrick>SPINE01: cfg> clear ospf neighbor instance default ipv6 instance-id 0 area 0 interface ifl-0/0/0/1
Triggered clear neighbor successfullyClear OSPF Statistics
Clear the OSPF statistics for all instances or a specified instance.
Syntax:
clear ospf statistics <options>
| Option | Description |
|---|---|
- |
Without any option, the command clears all the OSPF statistics. |
instance <instance-name> |
Clears OSPF statistics information for the specified instance. |
instance <instance-name> <afi> |
Clears OSPF statistics for the specified address family of the specified instance. Supported AFI values are 'ipv4' and 'ipv6'. When using an IPv6 address family with OSPFv3, an instance ID ranging from 0 to 31 must be specified. |
instance <instance-name> <afi> area <area-id> |
Clears OSPF statistics for the specified area of the specified instance and address family. |
instance <instance-name> <afi> area <area-id> interface <interface-name> |

Cleared statistics for all ipv6 neighbors under Instance [default] Area [0.0.0.0] Interface [ifl-0/0/0/1]Clear OSPF Database
Clear the OSPF database for all instances.
Syntax:
clear ospf database <options>
| Option | Description |
|---|---|
- |
Without any option, the command clears all the OSPF database information. |
<afi> |
Clears OSPF database for the specified address family. Supported AFI values are 'ipv4' and 'ipv6'. Supported AFI values are 'ipv4' and 'ipv6'. When using an IPv6 address family with OSPFv3, an instance ID ranging from 0 to 31 must be specified. |
<afi> instance <instance-name> |
Clears OSPF database for the specified area of the specified instance and address family. |
Example:
supervisor@rtbrick>SPINE01: cfg> clear ospf database ipv6 instance default instance-id 0
Triggered clear database successfully
