1826 ExtremeWare 7.7 Command Reference Guide
IGP Commands
configure ospf timer
configure ospf [vlan <vlan name> | area <area identifier> | virtual-link
<routerid> <area identifier>] timer <retransmit interval> <transit delay>
<hello interval> <dead interval> {<wait timer interval>}
Description
Configures the timers for one interface or all interfaces in the same OSPF area.
Syntax Description
Default
• retransmit interval—Default: 5
• transit delay—Default: 1
• hello interval—Default: 10
• dead interval—Default: 40
• wait timer interval—Default: dead interval
Usage Guidelines
Configuring OSPF timers and authentication on a per-area basis is a shorthand for applying the timers
and authentication to each VLAN in the area at the time of configuration. If you add more VLANs to
the area, you must configure the timers and authentication for the new VLANs explicitly.
Example
The following command sets the timers on the virtual link in area 0.0.0.2:
configure ospf virtual-link 6.6.6.6 0.0.0.2 timer 10 1 20 200
History
This command was available in ExtremeWare 2.0.
vlan name Specifies a VLAN name.
area identifier Specifies an OSPF area.
routerid Specifies a router number.
retransmit interval Specifies the length of time that the router waits before retransmitting an LSA
that is not acknowledged. The range is 0 - 3,600 seconds.
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 seconds.
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.
