retransmit-interval (OSPF virtual link)
retransmit-interval (OSPF virtual link)
To specify the time between link-state advertisement (LSA) retransmissions for adjacencies that belong
to the virtual link, use the retransmit-interval command. To return to the default, use the no form of
this command.
retransmit-interval seconds
retransmit-interval
Syntax Description
Command Default 5 seconds
Command Modes Virtual link configuration mode
Command History
Usage Guidelines Use this command to set the LSA retransmission time. If a router receives no acknowledgment that an
LSA was received, the router resends the LSA at the retransmission interval.
You should set this value larger for virtual links.
This command requires the LAN Enterprise Services license.
Examples This example shows how to set the retransmit interval value to 8 seconds:
switch# configure terminal
switch(config)# router ospf 109
switch(config-router)# area 33 virtual-link 192.0.2.2
switch(config-router-vrf)# retransmit-interval 8
switch(config-router-vrf)#
Related Commands
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
area virtual-link Creates a virtual link in an OSPF area.
