ip ospf retransmit-interval
This command specifies the time between resending link-state advertisements
(LSAs). Use the no form to restore the default value.
Syntax
ip ospf retransmit-interval seconds
no ip ospf retransmit-interval
seconds - Sets the interval at which LSAs are retransmitted from this
interface. (Range: 1-65535)
Command Mode
Interface Configuration (VLAN)
Default Setting
5 seconds
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.
• 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.
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.
