configure ospf virtual-link timer

configure ospf virtual-link router-identifier area-identifier timer retransmit-interval transit-delay hello-interval dead-interval


Configures the timers for a virtual link.

Syntax Description

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 1–3,600 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.


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.


The following command sets the timers on the virtual link in area and remote router ID

configure ospf virtual-link timer 10 1 20 200
