Cisco Multiservice Switching Networks

Chapter 6. MPLS Implementation and Configuration

In this chapter and Chapter 7, "Practical Applications of MPLS", we will implement an Multiprotocol Label Switching (MPLS) network detailing the configuration steps and linking them to all the concepts you already know. The approach of these two chapters is the one a service provider or Enterprise network engineer would take. In this chapter we will implement the MPLS network that will serve as the foundation for services built on top of it. Different implementations of ATM MPLS LSRs and eLSR will build this MPLS network. In Chapter 7, we will configure a basic MPLS VPN. Finally, we will enable quality of service following the DiffServ model.

An important part of this chapter is that in addition to covering BPX-8600, IGX-8400, MGX-8850, and other platforms, a generic configuration model is introduced. Along with that common configuration model, we will present a summary of commands. The final part of MPLS implementation and configuration will be spent covering some troubleshooting scenariosnotably, Label VC (LVC) starvation.
