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.

`vlan-name`	Specifies a VLAN name.
all	Specifies all VLANs.
`retransmit-interval`	Specifies the length of time that the router waits before retransmitting an LSA that is not acknowledged. The range is 1 - 3,600.
`transit-delay`	Specifies the length of time it takes to transmit an LSA packet over the interface. The range is 0 - 3,600 seconds.
`hello-interval`	Specifies the interval at which routers send hello packets. The range is 1 - 65,535 seconds.
`dead-interval`	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.
`wait-timer-interval`	Specifies the interval between the interface coming up and the election of the DR and BDR. Usually equal to the dead timer interval.

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.

The following command configures the OSPF wait interval on the VLAN accounting:

configure ospf vlan accounting timer 10 15 20 60 60
