Course Summary
his two-day course provides students with the foundational knowledge required to work with the Juniper Apstra System and to manage data center networks with Juniper Apstra software. This class will provide students with the knowledge to operate and manage Juniper Apstra. Students will be given a background on modern data center design and Intent-Based Networking concepts. The course covers the Juniper Apstra architecture and its data center reference architecture including the designing, building, deploying, and automation of a 3-stage IP fabric with VXLAN overlay. The course goes on to cover navigation of the Juniper Apstra user interface including creating resources, designs, templates, and instantiating blueprints (a running network). After teaching you to use Juniper Apstra to build a running data center, the course reviews the operational tools for managing a system with Juniper Apstra including basic troubleshooting, maintenance mode, adding and removing nodes from a fabric, rolling back an entire network (Time Voyager), creating off-box agents, configuring group-based policies, connectivity templates, and performing Intent-Based Analytics (IBA). Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring an IP fabric using Juniper Apstra.
