Chapter 8. MPLS Traffic Engineering
What You Will Learn
By the end of this chapter, you should know and be able to explain the following:
What the advantages of MPLS TE are
How OSPF and IS-IS have been extended for MPLS TE
How TE LSPs and their costs are calculated
How traffic is mapped to MPLS TE tunnels
How Fast ReRoute for link and node protection works
