This chapter covers the following topics:

  • MPLS Operation—. This section describes the operation of MPLS networks and discusses the advantages of MPLS over conventional Layer 3 forwarding.

  • MPLS Node Architecture—. This section describes the architecture of MPLS nodes. These nodes include MPLS-enabled routers and ATM switches. MPLS nodes consist of a control plane and a forwarding plane.

  • MPLS Elements—. The various elements that constitute an MPLS network are described here. The MPLS Label-Switched Router (LSR), Label-Switched Path (LSP) mechanisms, and the workings of the Label Distribution Protocol (LDP) are explained in detail.

  • Loop Survival, Detection, and Prevention in MPLS—. This section covers the effect of routing ...
