OSPF Reference Bandwidth on Huawei

I have R1 who has a G0/0/0 and a S4/0/0/0 interface. The reference bandwidth (which is 108 bps) can be changed on Huawei routers. The reason of changing it, is because when you have a Gigabit Ethernet interface (like in our case) we will have issues because the reference bandwidth is 100 Mbps and the Gigabit Ethernet is 1000 Mbps. The lowest value of the cost can be 1, that’s why we need to increase the reference bandwidth when we need to use Gigabit Ethernet interfaces or bigger interfaces, otherwise they will do load balancing with interfaces having 100 Mbps speed because they also will have a cost of 1.

For now, let’s check the IP addresses that are set on R1’s interfaces.

Let’s enable OSPF on R1 and advertise the connected network to it.
