configure ospf vlan [<vlan-name> | all] timer <retransmit-interval> <transit-delay>
<hello-interval> <dead-interval> {<wait-timer-interval>}
You can configure the following parameters:
• Retransmit interval
—The length of time that the router waits before retransmitting an LSA that is
not acknowledged. If you set an interval that is too short, unnecessary retransmissions will result.
The default value is 5 seconds.
• Transit delay
—The length of time it takes to transmit an LSA packet over the interface. The transit
delay must be greater than 0.
• Hello interval
—The interval at which routers send hello packets. Smaller times allow routers to
discover each other more quickly, but also increase network traffic. The default value is 10 seconds.
• Dead router wait interval (Dead Interval)
—The interval after which a neighboring router is
declared down due to the fact that hello packets are no longer received from the neighbor. This
interval should be a multiple of the hello interval. The default value is 40 seconds.
• Router wait interval (Wait Timer Interval)
—The interval between the interface coming up and the
election of the DR and BDR. This interval should be greater than the hello interval. If it is close to the
hello interval, the network synchronizes very quickly, but might not elect the correct DR or BDR. The
default value is equal to the dead router wait interval.
NOTE
The OSPF standard specifies that wait times are equal to the dead router wait interval.
