OSPF measurement method

The default reference bandwidth value is 100M. When the result of the calculation has decimal places, only integer bits are used. When the result is less than 1, the cost is equal to 1, can you explain this in detail?

Now the bandwidth of the network is at least GE. In large metropolitan area networks, the egress bandwidth is at least 100G, and the value of the reference bandwidth can be set larger.

Is there any difference if we don't set the bandwidth-reference?

Good

Configuring directly on the interface is a good way to measure OSPF

An interface cost=reference bandwidth/actual bandwidth

The default reference bandwidth value is 100M. When the calculation result has decimal places, only integer digits are used. When the result is less than 1, the cost is equal to 1.

2. Two ways to change the cost:

a/ directly configured on the interface

<Huawei> system-view

[Huawei] interface gigabitethernet 1/0/0

[Huawei-GigabitEthernet1/0/0] ospf cost 65

b/Modify the reference bandwidth (all routers need
