OSPF Commands 239
Default Configuration
The default value is 5 seconds.
Command Mode
OSPF virtual link configuration
User Guidelines
When a router sends an LSA to its neighbor, it keeps the LSA until it receives back the
acknowledgment message. If the router receives no acknowledgment, it resends the LSA. The
setting of this parameter should be conservative to prevent unnecessary retransmissions.
Example
The following example specifies the time between link-state advertisement (LSA) retransmissions
for adjacencies belonging to the OSPF virtual link interface as 10 seconds.
transmit-delay
The transmit-delay ospf virtual link interface configuration command sets the estimated time
required to send a link-state update packet on the OSPF virtual link interface. To return to the
default value, use the
no form of this command.
Syntax
transmit-delay seconds
no transmit-delay
• seconds —Time (in seconds) required to send a link-state update. (Range: 1- 3600)
Default Configuration
The default value is 1 second.
Command Mode
OSPF virtual link configuration
User Guidelines
Link-state advertisements (LSAs) in the update packet must have their ages incremented by
the amount specified in the seconds argument before transmission. The value assigned
should take into account the transmission and propagation delays for the interface.
