Chapter Unicast Routing Commands
ip ospf retransmit-interval
ip ospf retransmit-interval
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
Syntax Description
Command Default 5 seconds
Command Modes Interface configuration mode
Command History
Usage Guidelines 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.
Examples This example shows how to set the retransmit interval value to 8 seconds:
switch# configure terminal
switch(config)# interface ethernet 1/2
switch(config-if)# no switchport
switch(config-if)# ip ospf retransmit-interval 8
switch(config-if)#

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.
Release Modification
5.0(3)A1(1) This command was introduced.
Command Description
copy running-config
startup-config
Saves the configuration changes to the startup configuration file.
ip ospf transmit-delay Sets the estimated time to transmit an LSA to a neighbor.
show ip ospf Displays OSPF information.
