Chapter 8. WAN Protocols over MPLS Case Studies

Setting up WAN over MPLS pseudowires

Introducing WAN protocols over MPLS

Configuring WAN protocols over MPLS case studies

Advanced WAN AToM case studies

This chapter covers the functional details and implementation of the transport and tunneling of different WAN protocols over Multiprotocol Label Switching (MPLS). Building upon the WAN data-link protocol primer introduced in Chapter 5, "WAN Data-Link Protocols," and the overview of Any Transport over MPLS (AToM) introduced in Chapter 6, "Understanding Any Transport over MPLS," this chapter explores the operation, configuration, and troubleshooting of High-Level Data Link Control (HDLC), PPP, Frame Relay, and AToM. It also covers the different operational modes of these protocols.

Similarly to previous chapters, this chapter walks you through the different building blocks and detailed configuration and operation aspects of WAN protocols over MPLS. Several case studies present the service provider side of the configuration. Although customer premise configurations are included, they do not vary from traditional Layer 2 transport technologies, because WAN over MPLS is transparent to the end user.
