Description

The Cisco IOS XR Layer 3 VPN Implementation and Verification (IOSXR301) v1.0 is a 2-day instructor-led course that introduces learners to how to implement and verify Layer 3 VPN Services on a Cisco IOS XR Software–based network.
The course is part of a portfolio of courses to enable customers to support and maintain their Cisco IOS XR platforms. These platforms include the Cisco ASR 9000 Series Aggregation Services Routers and Carrier Routing System CRS-1, CRS-3, and CRS-X, and Cisco Network Convergence System Series (NCS) 1000, 4000, 5000, 5500, and 6000.

When delivered online, as a virtual-instructor-led training (VILT), the course is duration is extended to 4 days.

Objectives

Upon completing this course, the learner will be able to meet these overall objectives:
  • Implement and verify Label Distribution Protocol (LDP) in the core of a service provider network, including implementing LDP session protection, LDP nonstop routing, graceful restart, LDP-IGP synchronization, LDP auto configuration, and MPLS Operations, Administration, and Maintenance (OAM) solution
  • Implement and verify intra-AS Layer 3 VPNs using Multiprotocol Border Gateway Protocol (MP-BGP) in core network and various PE-CE route distribution methods, including using static routing and BGP
  • Implement and verify inter-AS Layer 3 VPNs using various methods including inter-AS Layer 3 VPN options A, B, and C
