15.26 ip ospf retransmit-interval
To specify the time between link-state advertisement (LSA) retransmissions for adjacencies belonging 
to the interface, use the ip ospf retransmit-interval command in interface configuration mode. To 
return to the default value, use the no form of this command. 
 
Command Syntax 
ip ospf retransmit-interval seconds 
no ip ospf retransmit-interval 
seconds
Time (in seconds) between retransmissions. It 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. 
 
Default 
5 seconds
 
Command Mode 
Interface configuration
 
Usage 
When a router sends an LSA to its neighbor, it keeps the LSA until it receives back the 
acknowledgment message. If the router receives no acknowledgment, it will resend the LSA. The 
setting of this parameter should be conservative, or needless retransmission will result. The value 
should be larger for serial lines and virtual links. 
 
Examples 
The following example sets the retransmit interval value to 8 seconds: 
interface eth-0-1 
 ip ospf retransmit-interval 8
