<retransmit-interval> <transit-delay> <hello-interval> <dead-interval>
Description
Configures the timers for a virtual link.
Syntax Description
Default
●

Usage Guidelines
Configuring OSPF timers 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 and remote router ID 6.6.6.6:
configure ospf virtual-link 6.6.6.6 0.0.0.2 timer 10 1 20 200
History
This command was first available in ExtremeWare XOS 10.1.
router-identifier
Specifies the router ID of the other end of the link.
area-identifier
Specifies an OSPF area.
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 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.
