Usage Guidelines

Use the ip ospf transmit-delay command to set the estimated time needed to send an LSA update packet. OSPF increments the LSA age time by the transmit delay amount before transmitting the LSA update. You should take into account the transmission and propagation delays for the interface when you set this value.

This command requires the LAN Base Services license.


This example shows how to set the transmit delay value to 8 seconds:

switch(config)# interface ethernet 1/2 
switch(config-if)# no switchport
switch(config-if)# ip ospf transmit-delay 8
