The Cisco IOS XRLayer 3 VPN Implementation and Verification (IOSXR301) v1.1 course shows you how to implement and verify Layer 3 VPN services on a Cisco®Internetwork Operating System (IOS) XR network. You will learn how to 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 (Interior Gateway Protocol) synchronization, LDP auto configuration, and Multiprotocol Label Switching (MPLS) Operations, Administration, and Maintenance (OAM) solutions. You will also learn how to implement and verify intra-AS Layer 3 VPNs using MP-BGP (Multiprotocol Border Gateway Protocol) in core network and various Provider Edge–Customer Edge (PE-CE) route distribution methods, including using static routing and BGP. And you will learn how to implement and verify inter–Autonomous System (AS) Layer 3 VPNs using various methods including inter-AS Layer 3 VPN options A, B, and C.

This course is part of a portfolio of courses designed to help you support and maintain Cisco IOS®XR platforms, including Cisco ASR 9000 Series Aggregation Services Routers and Carrier Routing System CRS-1, CRS-3, and CRS-X; and Cisco Network Convergence System (NCS) Series 1000, 4000, 5000, 5500, and 6000.
