Command Usage
A router will resend an LSA to a neighbor if it receives no
acknowledgment. The retransmit interval should be set to a conservative
value that provides an adequate flow of routing information, but does not
produce unnecessary protocol traffic. Note that this value should be
larger for virtual links.
Example
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 transmit-delay seconds
no ip ospf transmit-delay
seconds - Sets the estimated time required to send a link-state update.
(Range: 1-65535)
Command Mode
Interface Configuration (VLAN)
Default Setting
1 second
Command Usage
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. The transmit delay
must be the same for all routers attached to an autonomous system.
Example
Console(config)#interface vlan 1
Console(config-if)#ip ospf retransmit-interval 7
Console(config-if)#
Console(config)#interface vlan 1
Console(config-if)#ip ospf transmit-delay 6
Console(config-if)#
