Построение MPLS VPN 3 уровня под управлением Junos

Этот трехдневный курс был разработан для ознакомления слушателей с возможностями построения сетей L3 VPN (Layer 3 VPN) на основе технологии MPLS и соответствующими примерами настройки оборудования Juniper. Курс включает обзор концепций L3 VPN на основе MPLS, масштабирование сетей L3 VPN, интернет-доступ, межпровайдерские L3VPN, мультикаст для L3VPN. Курс также описывает характерные именно для операционной системы Junos виртуальные маршрутизаторы для L3 VPN. В лаборатории используется JunOS версии 16.1R3.10.

Примеры и лабораторные работы дают слушателям возможность приобрести опыт в настройке и мониторинге Junos и работы устройств.
