Course Objectives
After successfully completing this course, students should be able to: • Explain the reasons MPLS was originally created, and the applications offered by label-switched paths. • Describe the structure of an MPLS label, the mechanics of the data plane, and the protocols that can advertise labels. • Configure static LSPs, verify the routing tables they populate, and explain the label actions these LSPs perform. • Explain the purpose and advantages of RSVP, then configure a service provider network to host RSVP LSPs. • Configure and verify a basic RSVP label-switched path. • Explain the purpose of the MPLS traffic engineering database, and create LSPs that use this database to calculate a path. • Explain the purpose of RSVP bandwidth reservations, and how to configure an LSP to reserve bandwidth. • Explain the use-cases for RSVP LSP priority levels, and configure different priority levels of a variety of LSPs. • Explain how the Constrained Shortest-Path First algorithm can calculate traffic-engineered paths. • Explain the messages involved in tearing down, rerouting, and maintaining LSPs and RSVP sessions. • Describe how primary and secondary paths can be used in times of link and node failure. • Describe the advantages of RSVP local repair paths, and how to configure the one-to-one method of local repair, otherwise known as fast reroute. • Explain the mechanics, configuration, and verification of facility backup, otherwise known as link protection and node-link protection. • Explain how RSVP LSPs can automatically find and signal better, more optimal paths. • Explain how LSPs can gracefully move traffic to new paths with no downtime to the user. • Explain the mechanics by which LDP creates a full mesh of label-switched paths. • Configure and verify a basic LDP deployment in a service provider network. • Describe some important LDP enhancements and best practices that increase the integrity of real-world LDP deployments. • Explain how to configure LDP to advertise labels for more than just a router's loopback. • Explain how segment routing differs from RSVP and LDP, and configure segment routing as a replacement for LDP.

use-cases and configuration for primary and secondary paths • Identify the benefits and trade-offs of standby secondary paths • Show the advantage of pre-installing backup paths to the forwarding table o Lab 4: RSVP—Primary and Secondary Paths Module 13: RSVP—Local Repair, Part 1—One-to-One Backup, or Fast-Reroute • Demonstrate the downtime that can be caused by a link or node failure in an
