Clearing OSPF information

Clearing OSPF neighbors

You can use the following command to delete and relearn all OSPF neighbors, all OSPF neighbors for a specified interface or a specified
OSPF neighbor.
device# clear ip ospf neighbor all
Syntax: clear ip ospf [ vrf vrf-name ] neighbor all [ interface ] | interface | ip-address [ interface ]
Selecting the all option without specifying an interface clears all of the OSPF neighbors on the router.
The interface variable specifies the interface that you want to clear all of the OSPF neighbors on. The following types of interfaces can be
specified:
• ethernet unit/slot/port
• tunnel tunnel-ID
• veve-ID
The ip-address variable allows you to clear a specific OSPF neighbor.

Disabling and re-enabling the OSPF process

You can use the following command to disable and re-enable the OSPF process on a router.
device# clear ip ospf all
Syntax: clear ip ospf [ vrf vrf-name ] all
This command resets the OSPF process and brings it back up after releasing all memory used while retaining all configurations.

Clearing OSPF routes

You can use the following command to clear all OSPF routes or to clear a specific OSPF route.
device# clear ip ospf routes all
Syntax: clear ip ospf [ vrf vrf-name ] routes { all | ip-address/prefix-length }
Selecting the all option resets the OSPF routes including external routes, and OSPF internal routes.
The ip-address and prefix-length variables specify a particular route to delete and then reschedules the SPF calculation.
