reset ospf process
Parameters
| Parameter | Description | Value |
|---|---|---|
| process-id | Indicates the OSPF process ID. If the parameter is not specified, all OSPF processes are restarted. |
The value is an integer ranging from 1 to 65535. |
| flush-waiting-timer time | Specified the time when the LSA is generated. The parameter takes effect only when it is set. | The value is an integer that ranges from 1 to 40, in seconds. |
| graceful-restart | Indicates that graceful restart is enabled. | - |
Usage Guidelines
Usage Scenario
The reset ospf process command can be used to clear OSPF information to reset the board.
Configuration Impact
After the reset ospf process command is used to restart OSPF, the following situations may occur:
If the router ID is changed, a new router ID will take affect after the command is run.
Re-elect DR and BDR.
OSPF configuration will not be lost after OSPF restarts.
Precautions
Configuring the flush-waiting-timer parameter when OSPF starts, you can clear invalid LSAs within the set time before LSAs time out.
Whether all invalid LSAs on other wireless access controllers can be deleted is related to the set time.
When the wireless access controller restarts an OSPF process, the neighboring wireless access controller always reserves invalid LSAs. This occupies the memory of the system. These LSAs are deleted only when they expire, that is, when the LS age field in the LSA reaches 3600 seconds. After the reset ospf is used to restart an OSPF process and only when the router ID is changed, the wireless access controller generates an LSA in the set time and sets the LS age field to 3600 seconds. After receiving the LSA, other wireless access controllers delete the LSA immediately from their LSDBs. If a device does not send all the LSAs within the set time, other neighboring wireless access controllers still store some invalid LSAs.
