Getting started with Cisco Catalyst SD-WAN

Purpose and audience

Welcome to the Cisco Catalyst SD-WAN Getting Started Guide. This document serves as the foundational architectural blueprint and operational roadmap for Network Engineers, Solutions Architects, Systems Engineers, and WAN Administrators tasked with designing, deploying, and operating a modern Cisco Catalyst SD-WAN fabric. Whether executing a greenfield implementation or modernizing existing branch infrastructure, this guide provides the structured guidance necessary to move efficiently from initial architecture planning to a fully operational, policy-driven enterprise WAN overlay.

What to expect: Deployment phases and core steps

This guide walks through the complete deployment lifecycle of Catalyst SD-WAN across four progressive phases, detailing both the control-plane foundations and edge transport configurations:

  1. Architecture planning and control plane initialization: Discover how to establish your SD-WAN fabric baseline, validate enterprise prerequisites, and initialize secure control connections across the Cisco SD-WAN Manager (formerly vManage), SD-WAN Validator (vBond), and SD-WAN Controller (vSmart). You will configure root certificate chains, organization names, and control policies to form a zero-trust management plane.
  2. WAN edge bootstrapping and automating onboarding: Learn the step-by-step mechanisms for provisioning Catalyst 8000 series routers and virtual edge instances. This includes configuring Automated Network Onboarding via Plug and Play (PnP), generating boostrap configuration files, establishing WAN transport interfaces across MPLS and public internet, and verifying bidrectional control connections. 
  3. Centralized configuration and policy architecture: Transition from on-box management to scalable orchestration. This section details how to build modular Configuration Groups and Feature Templates to standardize system settings, BGP/OSPF dynamic routing, and VPN segmentation (Service and Transport VPNs). You will also learn how to author and activate Centralized Application-Aware Routing (AAR) policies to dynamically direct traffic based on real-time latency, jitter, and packet loss thresholds.
  4. Day-2 validation, telemetry, and operational health: Complete your deployment with operational best practices. Learn how to verify end-to-end data plane encryption over BFD-monitored IPsec tunnels, leverage SD-WAN Manager health dashboards for live traffic path inspection and configure streaming telemetry to maintain ongoing network visibility and automated troubleshooting.

Recommended skills and prerequisites for success

To maximize the value of this guide and achieve successful deployment outcomes, readers should possess:

  • Enterprise routing and topologies: Solid working knowledge of dynamic routing protocols (BGP multi-homing, OSPF area design, route redistribution) and hybrid WAN architectures (dual-homed DIA, MPLS, 4G/5G).
  • Security and tunneling fundamentals: Conceptual and practical familiarity with IPsec encapsulation, TLS/DTLS control protocol mechanics, and PKI/X.509 certificate management.
  • Management plane navigation: Experience operating web-based network management consoles, understanding object-based templates, and basic familiarity with network automation principles (REST APIs and JSON data formatting).
