This course discusses how label allocation and distribution function in a frame-mode network. Also covered are PHP and how the MPLS data structures are built. This course is essential to understanding the basics of how information is distributed and placed into the appropriate tables for both labeled and unlabeled packet usage.

This course presents LDP convergence issues and describes how routing protocols and MPLS convergence interact. This course concludes with a look at link failure, convergence after a link failure, and link recovery. Understanding the convergence times for LDP is important, as is understanding how routing protocols interact with MPLS. This information will ensure a clear understanding of how the various routing tables are built and refreshed during and after a link failure and how recovery in an MPLS network takes place.

This course explains the Cisco IOS platform-switching mechanisms by reviewing standard IP switching and Cisco Express Forwarding switching, including configuration and monitoring commands. It is important to understand the role that the Cisco Express Forwarding switching plays in an MPLS network. Cisco Express Forwarding must be running as a prerequisite to implementing MPLS on a Cisco router. Therefore, an understanding of the purpose and function of Cisco Express Forwarding will provide an awareness of how the network uses Cisco Express Forwarding information when forwarding packets. This course describes how to configure frame-mode MPLS on Cisco IOS platforms. The mandatory configuration tasks, as well as commands and their correct syntax, are discussed in this course. The course also covers some advanced configurations, such as label-switching MTU, IP TTL propagation, and conditional label distribution. Also discussed in this course is the operation of frame-mode MPLS over switched WAN media.

This course describes the procedures for monitoring MPLS on Cisco IOS platforms. The course lists syntax and parameter descriptions; examines interfaces, neighbor nodes, and the LIB and LFIB tables; and outlines the usage guidelines for the commands. Knowing which commands, you can use to verify correct operation of MPLS in the network is important. The information here will help you when you encounter problems with frame-mode interfaces that have MPLS running in the network. This course also looks at some of the common issues that arise in MPLS networks. For each issue that is discussed, a troubleshooting procedure is recommended to resolve the issue. Knowing which commands, you can use to verify correct operation of MPLS in the network is important. The information here will help you when you encounter problems with frame-mode interfaces that have MPLS running in the network.
