What is SD-WAN ? 

Software-Defined WAN (SD-WAN) is an overlay architecture that overcomes the biggest drawbacks of traditional 

WAN. SD-WAN builds a secure, unified connectivity over any transport (MPLS, Broadband, LTE, VSAT etc.)

and provides simplified operations with centralized management, policy control and application visibility 

across the enterprise.

Significance of Viptela 

The Most Deployed SD-WAN in Global 1000 Companies .

With SD-WAN built on the Viptela Fabric, enterprises can provide secure connectivity everywhere, deploy

new services and applications faster, and drastically simplify operational complexity in the WAN.

In this course you will find explanation of Viptela Fabric & how to deploy control plan with lab & Data plan (Theory ) .

The Cisco® SD-WAN solution offers a complete SD-WAN fabric with centralized management and security built in, creating a secure overlay WAN architecture across campus, branch, and data center and multicloud applications. The software solution runs on a range of SD-WAN routers across hardware, virtual, and cloud form factors.

Cisco SD-WAN builds on the architecture called Secure Access Service Edge (SASE). WAN security and features today must be distributed, cloud-based, flexible, and agile. Cisco SD-WAN is the industry’s first fully integrated SASE offering that combines best-of-breed SD-WAN with the cutting-edge Cisco Umbrella Cloud Security portfolio.

After connecting to Cisco SD-WAN, each network device can find the best path to the applications that reside in the data center or multicloud. Cisco SD-WAN can use any transport method (satellite, broadband, MPLS, 5G/LTE) from any location (core, edge, cloud) for any network service (security, application Quality of Experience [QoE], voice). Through OMP, Cisco SD-WAN supports both common and advanced routing protocols that are necessary for managing networks across the WAN and cloud, such as Border Gateway Protocol (BGP), Enhanced Interior Gateway Routing Protocol (EIGRP), Equal-Cost-Multi-Path (ECMP) routing, Open Shortest Path First (OSPF), Virtual Router Redundancy Protocol (VRRP), and IPv6. Cisco SD-WAN provides this flexibility in both full and partial mesh encrypted deliveries, allowing maximum customization based on business needs.
