Rick Gallahers MPLS Training Guide

Building Multi Protocol Label Switching Networks

This book introduces readers to mpls concepts, installation, migration, operation, inspection, and troubleshooting. It discusses specific router and switch platforms and includes such topics as frame-mode mpls, cell-mode mpls, label distribution protocol, tag distribution protocol, label distribution protocol migration, mpls configuration, traffic engineering, mpls vpns, mpls vpn deployment models, mpls vpn routing protocol support, multi-protocol bgp, mpls vpn configurations, mpls vpn integration, and mpls vpn management.

Network engineers running high-bandwidth networks ISPs needing to manage different kinds of data based on different plans and priorities. In addition, readers studying for the Cisco MPLS exam will find this a valuable reference.
