Video Tutorial – MPLS Traffic Engineering – LSP Attribute Lists

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.

  list          Re-list all of the attribute list entries
  lockdown      Lockdown the LSP--disable reoptimization
  no            Disable a specific attribute
  priority      Specify LSP priority
