EXAMPLE
This example assigns area 0.0.0.1 to the currently selected interface under
routing process “1.”
Console(config)#interface vlan 1
Console(config-if)#ipv6 router ospf tag 1 area 0.0.0.1
Console(config-if)#

Interface Configuration
ipv6 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.
SYNTAX
ipv6 ospf cost cost [instance-id instance-id]
no ipv6 ospf cost [instance-id instance-id]
cost - Link metric for this interface. Use higher values to indicate
slower ports. (Range: 1-65535)
instance-id - Identifies a specific OSPFv3 routing process on the
link-local network segment attached to this interface.
(Range: 0-255)

COMMAND USAGE
◆ 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 interfaces. Therefore, if you
install a 10 Gigabit module, you may need to reset the cost for all other
VLAN interfaces with only 1 Gbps ports to a value greater than 1 to
reflect the actual interface bandwidth.
