So let's configure our two. Our two is going to be our route reflector router. We will enable BGP first BGP, hundred, no auto summary we'll add the neighbor information. Remote as hundred. For our one. There's one more command that we need to add his neighbor 192 168 12 to one Ralph reflected Client basically we are telling our two that our one is our route reflector client.
We will do the same thing for our three Let me check a IP interface of our three first 13 dot one remote 100 can see adjacencies already forming here 13 dot one route reflector client. And yes we are forming a Jason's is already Now artists relationship with our four, I'm just going to add these two lines here for our four. But technically we should not be doing this at all. If r four needs to establish a relationship with r two, it has to go with r three because the physical connection is with our three. And hence what we should be doing is our three should be the neighbor of our four. And basically it should be also a server, a secondary server or a secondary route reflector.
Over here I'm advertising the loopback network as well as the physical networks are the physical links of, of our two with its neighbors. I'm putting the mask. The exact mask should be put in for BGP to advertise this type of routes. Moving on to r1 We only have one neighbor with r1 between r1. So r1 is neighboring are two so it's the same configuration as when you establish ibgp peering also advertise all the other networks network one dot two dot zero and 192 168 dot 12 dot zero and the right mask. So as you can see, there's no much configuration on the client routers.
Let's configure our three No summary neighbors neighbor, it's going to be hard to that's advertise all the networks in our three. So three dot zero dot zero dot zero that's the loopback address and the and the actual interfaces that will be advertising We call them basically those are the one interfaces. And that's all we have to do with our three. Let's come to our for now. Route a PGP hundred no to summary neighboring RS three Come on line advertise on other networks is a calling to face so far for 192 168 dot three dot 43 dot zero mask 25525522550. So let's look, let's verify our tos IBG pee inflammation.
So show IP BGP, and we can see there's all the all the addresses out there listed, all the prefixes are there. And it looks pretty good. Now, as I can tell you that, you know, pinging is not gonna work between the different interfaces due to this, we have to use an interior routing protocol, or IGP, basically. But it looks good so far, we have achieved our purpose in this lab. I hope this was very informative for you. And my advice is that you you have to build your own lab with the similar instructions to to get the actual hands on experience.
Now I'm trying to pick one
