Résumé du cours
This three-day course provides students with the foundational knowledge required to work with the Juniper Apstra Freeform reference design and to manage networks with Juniper Apstra software. This class will provide attendees with the knowledge to build, operate, and manage a network using the Juniper Apstra Freeform features set. Attendees will be given a background on Jinja2 templating.
The course covers the Juniper Apstra Freeform reference design and including the designing, building, deploying, and automation of a centrally routed and bridged, 3-stage IP fabric with VXLAN overlay. The course begins with a review of Jinja2 templating and goes on to cover the relationship between configuration templates, device context, and property sets. Using this knowledge, a student will use the Juniper Apstra user interface to instantiate a Freeform blueprint (a running network). After teaching you to use Juniper Apstra to build a running network, the course takes the student through the process of deploying a centrally routed and bridged 3-stage IP fabric using Freeform. After deploying the Freeform blueprint the course reviews the operational tools for managing a system with Juniper Apstra including basic troubleshooting and day 2 operations like drain mode, adding and removing nodes from a fabric, rolling back an entire network (Time Voyager), querying the graph database, and performing Intent-based Analytics (IBA).
Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring an Freeform-based IP fabric using Juniper Apstra. This course is based on Juniper Apstra Release 4.1.1.
