Config Ospf Vlan Timer - Extreme Networks ExtremeWare Command Reference Manual

IGP Commands

config ospf vlan timer

config ospf vlan <vlan name> timer <retransmit tinterval> <transmit delay>
<hello interval [1-655191]> <dead interval> {<wait timer interval>}
Description
Configures the OSPF wait interval.
Syntax Description
vlan name
retransmit interval
transmit delay
hello interval
rdead interval
wait timer interval
Default
• retransmit interval--5 seconds.
• 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.
• transmit 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
routerdeadinterval. Under some circumstances, setting the waitinterval 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 hellointerval. The default value
is equal to the routerdeadinterval.
Example
The following command configures the OSPF wait interval on the VLAN accounting:
config ospf vlan accounting timer 10 15 20 60 60
950
Specifies a VLAN name.
Specifies the length of time that the router waits before retransmitting an LSA
that is not acknowledged.
Specifies the length of time it takes to transmit an LSA packet over the
interface.
Specifies the interval at which routers send hello packets.
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.
Specifies the interval between the interface coming up and the election of the
DR and BDR.
