IE Vol 1: Carrier Supporting Carrier - MPLS Enabled Complete

Nothing too fancy about this lab. About the only note worth mentioning is next-hop-self is required on the PE routers iBGP session. This is because the CE link is not advertised in OSPF, therefore the P routers don't have reachability to them. But, since we have the loopback interfaces in OSPF, the P routers have those links in their routing tables and build MPLS labels for them.
