So, I've been working on a lab exercise to redistribute bgp from across MPLS into an eigrp internal network. Thanks to this forum I learned that because two of my MPLS simulated devices were both using BGP AS 1 and that made them "internal" so I had to use "distribute internal". Okay so far.
Now the question is, in real life when I look at my MPLS network, each office uses BGP 1 as the AS for the local BGP process on that router, but it uses 65005 for the "neighbor".
In such a case, even though all my routers have BGP 1 for the AS, all their neighbors would be 65005...meaning they are not internal as's to themselves?
I'm trying to understand how 'global' or 'local' the AS number is. It stands to reason they can't be too far reaching as there are so few numbers to pick from, compared to the number of ISP's which sure must be using BGP....
