Open Shortest Path First (OSPF)

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.
• 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
show ip ospf
This command shows basic information about the routing configuration.
