Labs 1,2, and 3 done. INE Vol 1 - 2nd pass.

Decided to Vol 1 again from both vendors, 2nd time around is much easier but still tripping up on some silly mistakes.

I was able to do labs 1, 2, and 3 in a matter of an hour. I still made the silly mistake of not specifying bgp next-hop-self between the PEs... It's funny how quickly I forget, I even made a note of this at the end of lab 1 during my first pass.

on to the next one.
