2 Enter an IP interface number.
Enter cost (1-65535) [1]:
3 Enter the cost value for the interface. The default is calculated by the
Layer 3 Module.
Setting the Delay This command sets the OSPF interface transmit delay. The Layer 3 Module
adds the value of the transmit delay to all link state advertisements (LSAs)
that it sends out to the network. Set the transmit delay according to the
link speed: use a longer transmit delay time for slower link speeds.
The default delay is 1 second.
To set the transmit delay:
1 Enter the following at the top-level menu:
ip ospf interface delay
The following prompt is displayed:
Select IP interfaces (1-2|all):
2 Enter an IP interface number.

Setting the
Hello Timer
The interface hello timer determines how often the interface transmits
hello packets to neighbor routers on the network. Hello packets tell other
routers that the sending router is still active on the network. If a router
does not send hello packets for a period of time specified by the dead
interval, the router is considered inactive by its neighbors and routes from
the inactive router are marked as eligible for deletion. See “Setting the
Dead Interval”on page 95 for more information.
The default value for the hello timer is 10 seconds.
Set the hello timer to the same value for all routers on the network
segment, because they are in the same area.
To set the hello timer:
1 Enter the following at the top-level menu:
ip ospf interface hello
