Learning objectives for the Junos MPLS Fundamentals training course

  • 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 trafficengineered 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.
