Neighbor formation

- Now that we understand some fundamental information about BGP, including the different states and timers involved, let's configure BGP, and take a look at neighbor formation. We've got a very basic topology here. We have router one in autonomous system 65100, and we have router two in autonomous system 65200. Let's start our configuration on router one, and our interfaces are already configured with IP addressing. The first thing we need to do is initialize the BGP process. We'll go under global configuration mode on router one and say router BGP, followed by the autonomous system number. And locally you can see from our topology that is 65100. So we'll hit Enter for that. And once we do that you can see we're now in BGP configuration mode. An optional step here is to define the BGP router ID. And we discussed in a previous video with our BGP theory that this is a unique 32-bit number to identify our BGP router in the advertised prefixes. We can set that manually or we can allow…
