Hello @yo8-20
Cost = Reference Bandwidth / Interface Bandwidth
Default Reference Bandwidth is 100 Mbps
Adjust the reference bandwidth as needed for high-speed networks ?
router ospf 1
auto-cost reference-bandwidth 10000
--This sets the reference bandwidth to 10000 Mbps (10 Gbps).
In some cases, you may want to manually set the cost of a link, independent of its bandwidth. This can be useful for traffic engineering purposes. Use ip ospf cost command to manually set interface cost.
interface GigabitEthernet0/0
ip ospf cost 10
--This sets the OSPF cost of the GigabitEthernet0/0 interface to 10, regardless of its actual bandwidth.
