Course number: OP00493
Course duration: 4 days (including lectures and hands-on lab exercises)
Price: €3,200

Course overview

This hands-on instructor-led course explores the Nokia Data Center Fabric solution. It starts with a review of modern data center networking architectures and the advantages of using Layer 3 and BGP for routing. It describes the SR Linux architecture and the Nokia 7220/7250 IXR routers and introduces the Nokia Fabric Services System. Participants will make extensive use of the SR Linux CLI and learn how to configure and verify interfaces, as well as MAC-VRF and IP-VRF network instances. The course covers, in particular, the usage of BGP in a leaf-and-spine data center topology. It also provides a basic introduction to EVPN-VXLAN network overlays. In addition, participants will gain experience using SR Linux logging, monitoring, and filtering tools. Other topics include user management, TLS certificates to secure gNMI connectivity and for Zero Touch Provisioning (ZTP).The course concludes with an overview of the use and capabilities of the Fabric Services System.
