Example
Console(config)#interface vlan 1
Console(config-if)#ip ospf retransmit-interval 7
Console(config-if)#
ip ospf transmit-delay This command sets the estimated time to send a link-state update packet over an
interface. Use the no form to restore the default value.
Syntax
ip ospf [ip-address] transmit-delay seconds
no ip ospf [ip-address] transmit-delay
ip-address - This parameter can be used to indicate a specific IP address
connected to the current interface. If not specified, the command applies
to all networks connected to the current interface.
seconds - Sets the estimated time required to send a link-state update.

Command Usage
â—† LSAs have their age incremented by this delay before transmission. When
estimating the transmit delay, consider both the transmission and propagation
delays for an interface. Set the transmit delay according to link speed, using
larger values for lower-speed links.
â—† If this delay is not added, the time required to transmit an LSA over the link is
not taken into consideration by the routing process. On slow links, the router
may send packets more quickly than devices can receive them. To avoid this
problem, use the transmit delay to force the router to wait a specified interval
between transmissions.
Example
Console(config)#interface vlan 1
Console(config-if)#ip ospf transmit-delay 6
Console(config-if)#
