To specify the time between Open Shortest Path First (OSPF) link-state advertisement (LSA) retransmissions for adjacencies that belongs to the interface, use the ip ospf retransmit-interval command. To return to the default, use the no form of this command.
ip ospf retransmit-interval seconds
no ip ospf retransmit-interval

seconds
|
Time (in seconds) between retransmissions. The time must be greater than the expected round-trip delay between any two routers on the attached network. The range is from 1 to 65535 seconds. The default is 5 seconds.

This command was introduced.

Use the ip ospf retransmit-interval command to set the time between LSA retransmissions. When a router sends an LSA to its neighbor, it keeps the LSA until it receives an acknowledgment message from the neighbor. If the router receives no acknowledgment within the retransmit interval, the local router resends the LSA.
This command requires the LAN Base Services license.
This example shows how to set the retransmit interval value to 8 seconds:
