Configure Ospf Vlan Timer - Extreme Networks ExtremeWare XOS Command Reference Manual

configure ospf vlan timer

configure ospf vlan [<vlan-name> | all] timer <retransmit-interval>
<transit-delay> <hello-interval> <dead-interval> {<wait-timer-interval>}
Description
Configures the OSPF wait interval for a VLAN or all VLANs.
Syntax Description
vlan-name
retransmit-interval
transit-delay
hello-interval
dead-interval
wait-timer-interval
Default
retransmit interval—5 seconds.
●
transit delay—1 second.
●
hello interval—10 seconds.
●
dead interval—40 seconds.
●
wait timer interval—dead interval.
●
Usage Guidelines
Specify the following:
retransmit interval—If you set an interval that is too short, unnecessary retransmissions will result.
●
transit delay—The transit delay must be greater than 0.
●
hello interval—Smaller times allow routers to discover each other more quickly, but also increase
●
network traffic.
dead interval—This interval should be a multiple of the hello interval.
●
wait timer interval—This interval is required by the OSPF standard to be equal to the router dead
●
interval. Under some circumstances, setting the wait interval to smaller values can help OSPF routers
on a broadcast network to synchronize more quickly at the expense of possibly electing an incorrect
DR or BDR. This value should not be set to less than the hello interval. The default value is equal to
the router dead interval.
ExtremeWare XOS 11.3 Command Reference
Specifies a VLAN name.
Specifies the length of time that the router waits before retransmitting an LSA
that is not acknowledged. The range is 1 - 3,600.
Specifies the length of time it takes to transmit an LSA packet over the
interface. The range is 0 - 3,600 seconds.
Specifies the interval at which routers send hello packets. The range is 1 -
65,535 seconds.
Specifies the interval after which a neighboring router is declared down due to
the fact that hello packets are no longer received from the neighbor. The range
is 1 - 2,147,483,647.
Specifies the interval between the interface coming up and the election of the
DR and BDR. Usually equal to the dead timer interval.
