Основы MPLS в ОС Junos

Данный 2-дневный курс позволяет слушателям получить полное представление о технологии MPLS.
После вступления, рассматривающего технологию в целом и формат MPLS заголовка, курс подробно знакомит с принципами работы двух основных протоколов обмена метками: LDP и RSVP. Отдельный акцент делается на инжиниринг и защиту трафика в MPLS, включая Fast Reroute, Link/Node Protection, LDP Loop-Free Alternate.
Все темы курса будут подкреплены практическими лабораторными работами, которые позволят слушателям получить опыт настройки и мониторинга MPLS в операционной системе Junos.

After successfully completing this course, you should be able to:

• Describe the history and rationale for MPLS, as well as its basic terminology.
• Explain the MPLS label operations (push, pop, swap) and the concept of label-switched path (LSP).
• Describe the configuration and verification of MPLS forwarding.
• Describe the functionalities and operation of RSVP and LDP.
• Configure and verify RSVP-signaled and LDP-signaled LSPs.
• Select and configure the appropriate label distribution protocol for a given set of requirements.
• Describe the default Junos OS MPLS traffic engineering behavior.
• Explain the Interior Gateway Protocol (IGP) extensions used to build the Traffic Engineering Database (TED).
• Describe the Constrained Shortest Path First (CSPF) algorithm, its uses, and its path selection process.
• Describe administrative groups and how they can be used to influence path selection.
• Describe the default traffic protection behavior of RSVP-signaled LSPs.
• Explain the use of primary and secondary LSPs.
