Basic Layer2 MPLS VPNs

Ok, so as far as I am aware, Layer2 VPNs are not covered in the INE MPLS CoD, or at least, they're not in the first 25 lessons that i've watched. But, as it was something that I was interested in recreating, I did a little Google search, and found the Cisco documentation for such a configuration. It is relatively simple;

PE(config-if)#mpls l2transport route [destination-PE address] [Virtual Circuit id]

This then gets translated (certainly in the IOS that i'm using anyway) to;

PE(config-if)#xconnect [destination-PE address] [Virtual Circuit id] encapsulation mpls
