Prerequisites for the ENSDWI certification

Candidates should have a complete understanding of enterprise WAN design and routing protocol operation and be familiar with Transport Layer Security (TLS) and IP Security (IPSec). Completion of the Cisco SD-WAN Operation and Deployment (ENSDW) course or equivalent experience is recommended.

Key Topics Covered in ENSDWI

Architecture

The Cisco SD-WAN architecture is designed to provide a scalable, secure, and efficient network solution. It separates the control plane and data plane, allowing for centralized management and policy enforcement. It also enables flexible deployment options across data centers, branches, and cloud environments. The architecture includes key components such as

  • vManage (network management)
  • vSmart (control plane)
  • vBond (orchestration)
  • WAN Edge routers (data plane)

Controller Deployment

Controller deployment involves setting up and configuring the SD-WAN controllers:

  • vManage
  • vSmart
  • vBond

These controllers can be deployed on-premises or in the cloud, providing high availability and redundancy. The vManage controller offers a single-pane-of-glass interface for network management, while vSmart handles control plane policies, and vBond orchestrates the initial device authentication and connectivity.

Router Deployment

Router deployment focuses on onboarding WAN Edge devices using Zero Touch Provisioning (ZTP) and Plug and Play (PnP). This process includes configuring device templates, establishing secure connections with the controllers, and ensuring seamless integration into the SD-WAN fabric. Cisco SD-WAN supports both physical and virtual WAN Edge routers.

Policies

Policy configuration is a critical aspect of Cisco SD-WAN, enabling granular control over network traffic. Policies can be defined for traffic engineering, application-aware routing, and security enforcement. Advanced control and data policies allow administrators to optimize network performance, prioritize critical applications, and provide compliance with security requirements.

Security and Quality of Service

Cisco SD-WAN integrates robust security features, including application-aware enterprise firewalls, Intrusion Prevention Systems (IPS), URL filtering, and Cisco Advanced Malware Protection (AMP). Quality of Service (QoS) policies offer optimal application performance by prioritizing traffic based on predefined criteria. The solution also supports end-to-end encryption and segmentation to protect data integrity and confidentiality.

Management and Operations

The vManage controller simplifies Cisco SD-WAN management and operations, providing centralized configuration, monitoring, and troubleshooting capabilities. The platform offers rich analytics and visibility into network performance, enabling proactive management and rapid issue resolution. Automation features further simplify network operations, reducing the complexity and operational overhead associated with traditional WAN deployments.

Core Components of Cisco SD-WAN

Cisco SD-WAN

vEdge Cloud routers

vEdge Cloud is a software router platform and it supports the full range of capabilities available on physical vEdge router platforms. It can be used as a virtual machine in various private, public, and hybrid cloud computing environments. vEdge Cloud routers use Intel DPDK infrastructure for optimal performance on x86 platforms and can leverage AES-NI encryption offload technology for improved IPSec performance.

SD-WAN controllers

Cisco SD-WAN includes three main controller components:

  • vManage: The centralized network management system that provides a GUI interface for monitoring, configuring, and maintaining all Cisco SD-WAN devices and their connected links.
  • vSmart: The centralized control plane component responsible for distributing routes and policy information via the Overlay Management Protocol (OMP).
  • vBond: The orchestration component that performs initial authentication of devices and orchestrates connectivity between controllers and WAN Edge routers.

WAN Edge devices

These are physical or virtual routers that sit at the network edge and provide secure data plane connectivity among sites over one or more WAN transports. They handle traffic forwarding, security, encryption, quality of service (QoS), and routing protocols.

Cisco SD-WAN 20.3 code overview

Cisco SD-WAN Release 20.3.x introduced several new features and enhancements, including:

  • Improved security features such as application-aware enterprise firewalls, Intrusion Prevention Systems (IPS), and URL filtering
  • Enhanced cloud connectivity options
