You 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 synchronization, LDP auto configuration and MPLS Operations, Administration, and Maintenance (OAM) solution.

You also learn how to implement and verify intra-AS Layer 3 VPNs using MP-BGP (Multiprotocol Border Gateway Protocol) in core network and various PE-CE route distribution methods, including using static routing and BGP. Also, you learn how to implement and verify inter-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 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.
