Course overview

This course covers MPLS concepts, terminology and signaling protocols such as Label Distribution Protocol (LDP) and Resource Reservation Protocol with Traffic Engineering (RSVP-TE). It discusses the control-plane and the data-plane behavior of the protocols. The configuration and signaling of intra-area and inter-area MPLS tunnels with traffic engineering constraints such as admin groups, shared-risk groups, and maximum number of hops using RSVP-TE are covered in detail. It also covers tunnel resiliency approaches used by both RSVP-TE and LDP. Upon successfully completing this course, students will be familiar with the implementation, monitoring, and basic troubleshooting of an MPLS network. All use cases and lab exercises are based on the model-driven command-line interface (MD-CLI).

Course objectives

After completing the course, students should be able to:

  • Explain the basic concepts of MPLS technology such as forwarding equivalence classes (FECs), labels and label stacks, label distribution, LSPs, and MPLS packet forwarding
  • Describe the MPLS header structure and explain the label operations of pop, push, and swap
  • Explain how LDP works to distribute labels for FECs and establish LSPs
  • Describe traffic engineering and its advantage in an MPLS network
  • Identify the traffic engineering extensions made to the IGP routing protocols and understand how they are used with CSPF to establish traffic engineered LSPs
  • Demonstrate how RSVP-TE is used to establish traffic engineered LSPs using RSVP signaling messages to distribute labels, specify constraints for the LSP, and request LSP protection mechanisms
  • Describe the concept of a shared risk link group (SRLG) and its use in traffic engineering
  • Configure an MPLS-based core network using LDP, RSVP-TE, and hierarchical network using Inter-Area TE LSP
  • List the various LSP protection mechanisms (secondary/standby LSP, fast reroutes and LFA).
  • Configure RSVP-TE LSPs using each of the possible protection mechanisms
  • Describe MPLS for IP routing (MPLS shortcuts)
  • Configure 6PE on a network of 7750 SRs
  • Understand how to manage, monitor and perform basic troubleshooting of LDP/RSVP-TE-established LSPs on the Nokia 7750 Service Router (SR) and Nokia 7450 Ethernet Service Switch (ESS)
