You can configure the interface cost explicitly to specify the cost of sending a packet on an interface. Values are 1-65535.
This example configures the interface cost to be 20.
SEFOS(config)# interface vlan 10 SEFOS(config-if)# ipv6 ospf metric 20 SEFOS(config-if)# end
SEFOS# show ipv6 ospf interface vlan 10 Ospfv3 Interface Information Interface Name: vlan10 Interface Id: 41 Area Id: 0.0.0.6 Local Address: fe80::214:4fff:fe6c:628f Router Id: 10.0.0.1 Network Type: BROADCAST Cost: 20 State: BACKUP Designated Router Id: 10.0.0.8 local address: fe80::214:4fff:fe6c:d04d Backup Designated Router Id: 10.0.0.1 local address: fe80::214:4fff:fe6c:628f Transmit Delay: 1 sec Priority: 1 IfOptions: 0x0 Timer intervals configured: Hello: 10, Dead: 40, Retransmit: 5, Poll: 120 Demand Circuit: Enable Neighbor Probing: Enable Nbr Probe Retrans Limit: 10 Nbr Probe Interval: 120 Hello due in 4 sec Neighbor Count is: 1 Adjacent with neighbor 10.0.0.8
