Hello Lee
Looking a little deeper into the issue, looking at the router configurations, the router IDs of both R2 and R3 are indeed the same as both Lo interfaces are set to 2.2.2.2. So according to BGP route selection process, if the router IDs are the same, then the router will prefer the route with the lowest neighbour IP address. So between R2 and R3, the lowest neighbour IP address is indeed 192.168.12.2, so R2 will be chosen as the path.
So the following statement in the lesson has to be revised:
…because the Router ID is actually that of the loopback interface, but since those are the same, the neighbour IP address is used. The result is the same, but the lesson should clarify this. I will let @ReneMolenaar know about it…
Thanks for your help!
