Nokia SR Linux EVPN and Data Center Interconnect

Course number: OP00129
Course duration: 4 days (including lectures and hands-on lab exercises)
Price: $3,125

 

Course overview

This hands-on instructor-led course provides a complete understanding of EVPN on SR Linux. Ethernet Virtual Private Networks have become the technology of choice to implement flexible and resilient overlay networks for multi-tenancy in modern data centers.  

The course includes a review of the use cases for EVPN and explores the major building blocks, which are BGP in the control plane and VXLAN in the data plane. It explains the SR Linux implementation of EVPN based on IETF standards RFC 7432 and 8365. 

Extensive hands-on labs will teach you to configure and verify Layer 2 and Layer 3 EVPN overlay networks, including multi-homing capabilities. They cover basic troubleshooting capabilities such as log files, debug traces and monitoring live data traffic.

The course explains multi-site Data Center Interconnection (DCI) with SR Linux and demonstrates interoperability with the Nokia 7750 Service Router used as a DC/WAN gateway device.
 

Course objectives

After completing the course, students should be able to:
 
•    Describe the use cases for EVPN in the data center.
•    Explain the use of the different EVPN route types.
•    Describe the operations of a Layer 2 EVPN network service, including MAC protection, MAC duplication monitoring, and proxy-ARP.
•    Describe the operations of a Layer 3 EVPN network service, including IRB interfaces, anycast-gateway IP addresses and PE-CE BGP.  
•    Configure and verify Layer 2 and Layer 3 EVPNs with SR Linux.
•    Describe, configure, and verify All-Active and Single-Active L2 and L3 EVPN multi-homing scenarios.
•    Understand different approaches to interconnect multiple data centers over a WAN using EVPN.
