Cert Summit BGP Issue – SOLVED!

Wow! How interesting. I have never seen VIRL fail like that before. It was indeed a flawed loading of my configurations that was the issue with the demonstration. Check out how smoothly our intended configuration went after reloading the VIRL topology!

What is surprising about this whole thing was that I cannot believe BGP worked at all!
