EoMPLS transport case studies

Common troubleshooting techniques

Chapter 6, "Understanding Any Transport over MPLS," introduced you to the general concepts of Any Transport over MPLS (AToM). In this chapter, you learn operation and configuration of Ethernet over MPLS (EoMPLS), one of the draft-martini-based AToM technologies. EoMPLS offers a way to connect geographically dispersed Ethernet networks. By deploying EoMPLS in their core, service providers can implement Ethernet VPN services.

This chapter outlines important aspects of the EoMPLS technology and provides step-by-step configuration procedures for enabling EoMPLS, primarily on the service provider's side. As you already know from previous chapters, the Layer 2 VPN is transparent to the end customer, so the configuration required for the enterprise's devices is minimal.

The case studies included in this chapter do not concentrate on configuration specifics that are native to different platforms. Instead, they provide generic configuration for routers and switches.

Chapter 6. In some cases, simple references to these chapters are provided. In other cases (when necessary), certain concepts are reiterated.
