interface. Use the no form to restore the default value.
Syntax
ip ospf cost cost
no ip ospf cost

ports. (Range: 1-65535)
Command Mode
Interface Configuration (VLAN)
Default Setting
1
Command Usage
Interface cost reflects the port speed. This router uses a default cost of
1 for all ports. Therefore, if you install a Gigabit module, you may have
to reset the cost for all of the 100 Mbps ports to a value greater than 1.
Example

ip ospf dead-interval

Use this command to set the interval at which hello packets are not seen
before neighbors declare the router down. Use the no form to restore the
default value.
Syntax
ip ospf dead-interval seconds
no ip ospf dead-interval
Console(config)#interface vlan 1
Console(config-if)#ip ospf cost 10
