Chapters 1-2 explain how to set up a test environment. You learn how to install certificates to vBond, vManage, vSmart, and vEdge and how to set up underlay and Out-of-Band management network connections. Chapter 3 introduces a centralized control plane with the Overlay Management Protocol (OMP) running between vEdges and vSmart. Chapter 4 introduces the end-to-end control-plane processes and data-plane encapsulation over the SR-MPLS transport network. You also learn some of the basic concepts of the IS-IS Segment-Routing extension. Chapter 5 teaches how you can implement Hub and Spoke overlay topology by filtering TLOC routes using Centralized Policy. Chapter 6 discusses Feature Templates in which you set protocol and feature-specific values. Chapter 7 shows how to use TLOC Extension for transport network connection in dual-homed sites. Chapter eight discusses LAN side BGP routing. It also explains how you can build a Centralized Policy to filter out unnecessary OMP routes. Chapter 9 discusses how to do preference-based traffic engineering, again with Centralized Policy. Chapter 10 introduces Application-Aware Routing. The last chapter explains how to build a Direct Cloud Access (DCA), where the remote-sites user can access applications hosted in Cloud provider networks using the local Internet connection while all other traffic is sent over SD-WAN overlay tunnels. You will also learn how to filter DCA traffic with a centrally managed Zone-Based Firewall.
