Cisco happens to use the Reference BW and divides that by the interface BW to get a cost. You can configure the cost (or reference BW) to whatever you want. Since youe switches are connected in a line and have no other path you can manipulate these with no routing changes to see how...

The default reference bandwidth of 100 Mbps is used for OSPF cost calculation. For example, if we have an Ethernet interface (10 Mbps), the OSPF path cost value is 100 Mbps / 10 Mbps = 10. OSPF Default Interface Cost Values Here are the default Cost values for each interface type: ...
Cisco IOS XR software does not support type of service (ToS), so you can assign only one cost for each interface. In general, the path cost is calculated using the following formula: 108 / bandwidth (the default auto cost is set to 100 Mbps) This calculation is the default refere...

OSPF(Open Shortest Path First)是一种内部网关协议(IGP),用于路由选择以及网络发现。在OSPF协议中,开销值(Cost)被用来决定从一个路由器到另一个路由器的最佳路径,即路径的优先级。OSPF协议中,每个连接都有一个具体的开销值,通常是从1到65535的数字。普遍来说,开销值越小,路径越优先被选择。在计算路径的开销时...
If the device performing an SPF calculation is an ABR, the device needs to check only Type 3 LSAs in the backbone area. The device calculates AS external routes. AS external routes can be considered to be directly connected to the ASBR. Because the shortest path to the ASBR has been calcu...
