Lab 17 - quick and easy, down and dirty. Pretty straight forward and re-emphasizing the basics of configuring VRFs and route-targets, one little tricky thing was the use of the same AS number for BGP CE to PE peering. The solution accomplished it one way on the CE but I was also looking to do it on the PE as well... ie use as-override... wonder why they didn't use AS-OVERRIDE on the PE?
