Advanced Junos Service Provider Routing (AJSPR)

CODE: JUN_AJSPR

LENGTH: 5 day(s)

PRICE: €4 750,00

Description

his five-day course is designed to provide students with detailed coverage of OSPF, ISIS, BGP, and routing policy. Through demonstrations and hands-on labs, students will
gain experience in configuring, monitoring, and troubleshooting the Junos operating
system and in monitoring device and protocol operations.
This course uses Juniper Networks vMX Series Routers for the hands-on component, but
the lab environment does not preclude the course from being applicable to other
Juniper hardware platforms running the Junos OS. This course is based on the Junos OS
Release 19.3.

Audience

This course benefits individuals responsible for
implementing, monitoring, and troubleshooting
Layer 3 components of a service provider’s network.

Prerequisites
