A router will resend an LSA to a neighbor if it receives no
acknowledgment after the specified retransmit interval. 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.
◆
Set this interval to a value that is greater than the round-trip delay
between any two routers on the attached network to avoid unnecessary
retransmissions.

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.

link-local network segment attached to this interface.

◆
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
