The ospfv3 timer retransmit command specifies the interval for retransmitting the LSA on the interface instance.
The undo ospfv3 timer retransmit command restores the default value.
By default, the interval for retransmitting LSAs is 5 seconds.
ospfv3 timer retransmit interval [ instance instance-id ]
undo ospfv3 timer retransmit [ interval ] [instance instance-id ]
| Parameter | Description | Value |
|---|---|---|
| interval | Indicates the interval for retransmitting LSAs. | The value is an integer ranging from 1 to 3600, in seconds. |
| instance instance-id | Specifies the interface instance ID. | The value is an integer ranging from 0 to 255. The default value is 0. |
After sending an LSA to its neighbor, a switch needs to wait for the Ack packet from the neighbor. If the switch does not receive the Ack packet in the retransmission interval, the switch retransmits the LSA.
The interval for retransmitting LSA between the neighboring switches should not be set too short. Otherwise, it leads to unnecessary retransmission.
Before running this command on an interface, run the ospfv3 area command on the interface to enable OSPFv3.
