CartOne of the topics on the CCIE Service Provider blueprint is MPLS Traffic Engineering, also called TE. This technology was developed even earlier than L3VPN and was the first ‘feature’ based on label switching. The main advantage of TE is that you can prefer a path throughout the network that’s not chosen by an IGP or something else. By giving the tunnel specific priorities, like Bryan Bartik explained earlier (http://ipexpert.ccieblog.com/2009/05/27/mpls-te-bandwidth-and-priority/), you can ensure the path is given preference or even taken down when other ‘more important’ tunnels have better priority values.
