protocols ospf area <area-id> virtual-link <ipv4> retransmit-interval <interval>

Sets the retransmission interval for a virtual link.

set protocols ospf [ process pid ] area area-id virtual-link ipv4 retransmit-interval interval
delete protocols ospf [ process pid ] area area-id virtual-link ipv4 retransmit-interval
show protocols ospf [ process pid ] area area-id virtual-link ipv4 retransmit-interval

Unacknowledged LSAs are retransmitted at five-second intervals.

process pid
Specifies the PID of an IPv4 OSPF process.
area-id
The ID of the OSPF area being configured, expressed as an IP address or a decimal value.
ipv4
The area ID of the virtual link, expressed as an IPv4 address.
interval
The interval, in seconds, between the retransmission of unacknowledged LSAs. This interval must be the same for all nodes on the network. The interval ranges from 5 through 65535. The default interval is 5 seconds.

Configuration mode

protocols {
	ospf {
		area area-id {

}

Use this command to set the retransmission interval for a virtual link. This interval is the number of seconds before retransmitting an unacknowledged link-state advertisement (LSA).

When an OSPF router sends an LSA to a neighbor, the neighbor acknowledges receipt with a link-state acknowledgement (LS Ack) packet. If the local router fails to receive the expected LS Ack packet, it retransmits the LSA at the interval specified by this command. This interval must be the same for all nodes on the network.

Use the set form of this command to set the retransmission interval for a virtual link.

Use the delete form of this command to restore the default retransmission interval, which is 5 seconds, for a virtual link.

Use the show form of this command to display the retransmission interval for a virtual link.
