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 Base Services license.


This example shows how to set the retransmit interval value to 8 seconds:

switch(config)# router ospf 109
switch(config-router)# area 33 virtual-link
switch(config-router-vrf)# retransmit-interval 8
