The ospf timer retransmit command sets an interval for retransmitting LSA on an interface.
The undo ospf timer retransmit command restores the default interval for retransmitting LSA on an 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 device 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.
Do not set LSA retransmission intervals too short between adjacent routers. Otherwise, it leads to unnecessary retransmission.
Precautions
OSPF does not support the configuration on a null interface.
