Here are some key knowledge points when learning Cisco's Viptela SD-WAN solution:

1. Core Components

• vManage Network Management System: Centralized management for the entire SD-WAN network.
• vSmart Controller: Acts as the control plane, implementing policies and managing the network.
• vBond Orchestrator: Facilitates the discovery and authentication of vEdge routers.
• vEdge Routers: Deployed at branch locations to connect to the SD-WAN network.
• Optional vAnalytics Platform: Provides visibility into application and network performance.

2. Key Protocols and Technologies

• VPN (Virtual Private Network): Similar to VRF (Virtual Routing and Forwarding).
• OMP (Overlay Management Protocol): Control plane protocol similar to iBGP (Interior Border Gateway Protocol).
• GRE (Generic Routing Encapsulation) and IPSec (Internet Protocol Security): Used for tunneling and securing data.
• TLS/DTLS (Transport Layer Security/Datagram Transport Layer Security): For secure communication.

3. Configuration and Policies

• Templates: Used to configure network devices consistently.
• Policies: Define how traffic should be managed and routed across the network.

4. Use Cases

• Hybrid WAN: Combining MPLS, Internet, and 4G for bandwidth augmentation.
• Application-Aware Routing: Ensuring critical applications get the necessary bandwidth and performance.
• Direct Cloud Access: Connecting to IaaS (Infrastructure as a Service) and SaaS (Software as a Service) providers.
• Cloud Provisioning and Management: Managing cloud resources efficiently.

5. Prerequisites

• Understanding of GRE Tunneling: How GRE tunnels work over physical networks.
• Overlay and Underlay Networks: Knowledge of how these networks interact.
• iBGP and Route Reflectors: Familiarity with BGP attributes and best path selection.
• IPSec and DMVPN: Understanding of IPsec for secure tunnels and DMVPN for dynamic VPNs.

6. Additional Resources

• Cisco SD-WAN Documentation: Detailed guides and deployment manuals.
• Cisco SD-WAN Community: Forums and resources for troubleshooting and best practices.
• Cisco DevNet: API documentation and labs for vManage.
