In this LAB, I will show you how the equal cost load balancing happens on OSPF. I have already configured OSPF on all routers while having the reference bandwidth set to default. We should have the costs are following: [mepr-show rules=”319″...

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...

When configuring OSPF, you have the possibility to do load balancing in case you have 2 or more equal routes to the same destination network. And yes, the routes should be equal that means that they should have the same cost. But what is the cost exactly in OSPF? The...

I have started this chapter saying that some students think that only one DR should be for the whole OSPF area, while I have said that this is not true and the DR’s are elected based on number of segments. In this LAB I will show you how this happens. You can see, I...

In chapter 1, I have mentioned that in case you have a Point-to-Point network, then the concept of DR/BDR will not be applied because you only have 2 routers in the segment and it doesn’t matter which one to be the DR and which one will be the BDR. I just want to show...

I am still in the same LAB. Let’s imagine that we always want R1 to be the DR, and we do not any other router to participate in the DR election. What we can do in this case, is to give to R2 and R3 a priority of 0. Priority 0 means that R2 and R3 will never...
