NOTE: This digital course is part of the Cisco Digital Library and Networking CDL XL bundle but is not available for individual resell.
This course takes a close look at Multiprotocol Label Switching (MPLS) VPNs and enables you to plan, configure, and verify the implementation of MPLS-VPN. You learn about virtual routing and forwarding instances (VRFs), MPLS and Label Distribution Protocol (LDP) concepts, and customer edge-provider edge (CE-PE) routing protocols.
You also explore how MPLS labels are created for Layer 3 IPv4 prefixes, VPNv4 prefixes, and the differences between label switching and IPv4 prefix switching. You learn how those labels are distributed among routers using LDP, the various data structures used by Cisco Express Forwarding (CEF) to store prefix and label information, VPN label and transport label, and how labels are applied to packets and used to switch packets through an MPLS network.
In addition, you view various configuration examples, and in the lab exercises, you learn how to troubleshoot MPLS VPN networks.
