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.
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.

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