Command:

ip ospf retransmit-interval


Mode:

Router(config-if)#


Syntax:

ip ospf retransmit-interval seconds
no ip ospf retransmit-interval

 

Syntax Description:

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.

 

Command Description:

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.

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.

The default is 5 seconds.


Example:

The following example sets the retransmit interval value to 8 seconds:

Router(config)#interface ethernet 2
Router(config-if)#ip ospf retransmit-interval 8
