Leveraging Cisco IOS XR VPN Services [XRVPNS]

OVERVIEW

The Leveraging Cisco® IOS XR VPN Services (XRVPNS) course  teaches you how to implement and troubleshoot Layer 2 and Layer 3 Virtual Private Network services in a service provider network operating on Cisco IOS XR software. Cisco IOS XR is the foundational operating system of most service provider networks and operates Cisco’s service provider portfolio of network devices. You will learn how to implement a label switched network infrastructure for the enablement of VPN services using Multiprotocol Label Switching (MPLS) or Segment Routing (SR). You will also learn how to implement and troubleshoot both IPv4 and IPv6 Layer 3 VPN services and Multicast VPN services using IOS XR. In addition, you will learn how to implement Ethernet VPN (EVPN) services including EVPN Integrated Routing and Bridging (EVPN IRB) and EVPN-SR data center fabric. Finally, you will learn how to implement EVPN advanced features.

This course is worth 24 Continuing Education (CE) Credits.

OBJECTIVES

After completing this course you should be able to:

• Implement and configure MPLS and describe MPLS label propagation in service provider networks 
• Describe the main factors leading to the development and deployment of segment routing, describe the various types of segments that are used in segment routing, describe the Segment Routing Global Block (SRGB), and configure and verify Intermediate System to Intermediate System (IS-IS) and Open Shortest Path First (OSPF) segment routing operation 
• Implement and configure Segment Routing IPv6 
• Describe the components and functionality of Layer 3 MPLS VPNs implementation in Cisco IOS XR Software deployments 
• Identify the routing protocol and LDP information necessary for Layer 3 MPLS VPN troubleshooting 
• Discuss Multicast LDP (MLDP) implementation and troubleshooting method for Layer 3 multicast MPLS VPN 
• Implement MPLS VPN solutions for IPv6 environments 
• Describe common issues and fixes for provider edge to provider edge (PE-PE) and provider edge to customer edge (PE-CE) connectivity in an IPv6 MPLS VPN environment 
• Implement Layer 2 VPN operations in a service provider environment 
• Explain how EVPN gets around the problems that regular Layer 2 VPNs have, what the model for EVPN delivery is, and how to implement and troubleshoot EVPN solutions 
• Explain the advantages of EVPN IRB, how it is implemented, and how to troubleshoot problems when building EVPN IRB solutions 
• Demonstrate how to configure EVPN-SR data center fabric solutions 
• Explain advanced EVPN features to support network engineers in designing, implementing, and troubleshooting complex EVPN networks
