Nokia Data Center Fabric Fundamentals

Course number: OP004936
Course duration: 4 hours 
Price: €400

Course overview

This eLearning course reviews the modern data center networking architectures and the advantages of using Layer 3 and BGP for routing. It describes the architecture of SR Linux and the Nokia 7220/7250 IXR routers and introduces the Event Driven Automation (EDA) platform. Participants will make extensive use of the SR Linux CLI and learn how to configure and verify interfaces and routing protocols. Participants will also gain experience configuring L2 and L3 EVPN services and SR Linux logging, monitoring, and filtering features. Basic node management and Zero Touch Provisioning (ZTP) is covered, and the course concludes with an overview of the use and capabilities of EDA.
