ip ospf retransmit-interval

Use the ip ospf retransmit-internal command to specify the time between link-state advertisement (LSA) retransmissions for adjacencies belonging to the interface.

Use the no form of this command to return to the default value.

Command Syntax

ip ospf retransmit-interval INTERVAL (A.B.C.D) no ip ospf retransmit-interval (A.B.C.D)

INTERVAL= <3-65535> Specifies the time in seconds between retransmissions. Default interval value is 5 seconds.

A.B.C.D = IP address of the interface.

Command Mode Interface mode

Usage

After sending an LSA to a neighbor, the router keeps the LSA until it receives an acknowledgement. In case the router does not receive an acknowledgement during the set time (the retransmit interval value) it retransmits the LSA.

Set the retransmission interval value conservatively to avoid needless retransmission. The interval should be greater than the expected round-trip delay between two routers.

Examples

The following example shows setting the ospf retransmit interval to 6 seconds on the fxp0 interface for IP address 10.10.10.50. ospfd# configure terminal

ospfd(config)# interface fxp0

ospfd(config-if)# ip ospf ospf retransmit-interval 6 10.10.10.50

Related Commands ip ospf transmit-delay

Use the ip ospf transmit-delay command to set the estimated time it takes to transmit a link-state-update packet on the interface. Use the no form of this command to return to the default value.

Command Syntax

ip ospf transmit-delay DELAY (A.B.C.D) no ip ospf transmit-delay (A.B.C.D)

DELAY= <1-65535> Specifies the time taken, in seconds, to transmit a link-state-update. The default transmit delay value is 1 second.

A.B.C.D = IP address of the interface.

Command Mode Interface mode

Usage

The transmit delay value adds a specified time to the age field of an update. If the delay is not added, the time in which the LSA transmits over the link is not considered. This command is especially useful for low speed links. Add transmission and propagation delays when setting the transmit delay value.

Examples

The following example shows setting the OSPF transmit delay time to 3 seconds on the fxp0 interface for IP address 10.10.10.50. ospfd# configure terminal

ospfd(config)# interface fxp0

ospfd(config-if)# ip ospf transmit-delay 3 10.10.10.50
