Chapter 9. Case Studies

In this chapter, you learn about the following:

• Internet access network address translation implementations

• Multi-lite VRF and Internet access

• Layer 2 LAN best practice

This chapter provides deployment examples and lessons learned, highlighting theoretical discussion points from the previous chapters. We will examine Internet access and the hybrid model for providing both Internet and intranet services on a single provider edge, and will describe examples of applicability for a Multi-lite VPN routing/forwarding instance (VRF). Finally, we will provide examples for Layer 2 access over an MPLS-based network.
