This book provides you with guidelines to plan, design, roll out, and accomplish network migration activities with a variety of internetworking case studies. It considers both enterprise and service provider scenarios based on the expertise from Juniper Networks engineers. From Metro Ethernet migration approaches to comprehensive network protocol consolidation and integration, each case study covers JUNOS resources to ensure successful completion at each migration phase. In addition to an appendix of automation scripts and examples and guidelines for each step, the book also describes the modern challenges that evolve in IT networks.
