This is Video #6 of our MPLS Traffic Engineering series, which is designed to help viewers gain basic understanding of MPLS Traffic Engineering and how to configure TE tunnels in Cisco routers.

In this video, we will do a lab that demonstrates how to configure MPLS LSP Attribute lists that will provide flexibility to the tunnel path options.
