IP OSPF COST

ip ospf cost
Overview This command explicitly specifies the cost of the link-state metric in a router-LSA.
The no variant of this command resets the VLAN interface cost to the default.
Syntax ip ospf [<ip-address>] cost <1-65535>
no ip ospf [<ip-address>] cost
Default By default there is no static value set and the OSPF cost is automatically calculated
by using the
Mode Interface Configuration for a VLAN interface or a PPP interface.
Usage This command explicitly sets a user specified cost of sending packets out the
interface. Using this command overrides the cost value calculated automatically
with the auto-cost reference bandwidth feature.
The interface cost indicates the overhead required to send packets across a certain
VLAN interface. This cost is stated in the Router-LSA's link. Typically, the cost is
inversely proportional to the bandwidth of an interface. By default, the cost of a
VLAN interface is calculated according to the following formula:
reference bandwidth/interface bandwidth
To set the VLAN interface cost manually, use this command.
The following example shows setting ospf cost to 10 on VLAN interface vlan25
Example
for IP address 10.10.10.50
