ip ospf authentication (1769)
ip ospf cost
This command explicitly sets the cost of sending a protocol packet on an
interface, where higher values indicate slower ports. Use the no form to
restore the default value.

ip ospf [ ip-address ] cost cost
no ip ospf [ ip-address ] cost
ip-address - This parameter can be used to indicate a specific IP
address connected to the current interface. If not specified, the
command applies to all networks connected to the current interface.
cost - Link metric for this interface. Use higher values to indicate
slower ports. (Range: 1-65535)

◆
The interface cost indicates the overhead required to send packets
across a certain interface. This is advertised as the link cost in router
link state advertisements.
◆
Routes are assigned a metric equal to the sum of all metrics for each
interface link in the route.
◆
This router uses a default cost of 1 for all port types. Therefore, if any
VLAN contains 10 Gbps ports, you may want to reset the cost for other
VLANs which do not contain 10 Gbps ports to a value greater than 1.
