ip ospf cost
This command explicitly sets the cost of sending a packet on an interface. Use the
no form to restore the default value.
Syntax
ip ospf cost cost
no ip ospf cost
cost - Link metric for this interface. Use higher values to indicate slower
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
This command sets the interval at which hello packets are not s een 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
seconds - The maximum time that neighbor routers can wait for a hello
packet before declaring the transmitting router down. This interval must be
set to the same value for all routers on the network. (Range: 1-65535)
Command Mode
Interface Configuration (VLAN)
Default Setting
40, or four times the interval specified by the ip ospf hello-interval command.
Console(config)#interface vlan 1
