The ospf timer retransmit command sets the interval for retransmitting LSA on an interface.
The undo ospf timer retransmit command restores the default interval for retransmitting LSA on the interface.
By default, the interval time is 5 seconds.
| Parameter | Description | Value |
|---|---|---|
| interval | Specifies interval for retransmitting LSA on an interface. | The value is an integer ranging from 1 to 3600, in seconds. |

Usage Scenario
When a router transmits an LSA to its neighbor, it has to wait for the ACK packet from the neighbor. If no ACK packet is received from the neighbor in the LSA retransmission interval, this LSA is retransmitted.
Setting too short intervals of LSA retransmission between adjacent routers is not recommended. It leads to unnecessary retransmission.
Precautions
OSPF cannot be configured on the Null interface.
