JNCIP-ENT Enterprise Routing and Switching Certification Boot Camp (AJEX & AJER)

Prepare for your JNCIP-ENT certification with the convenience and savings of a 5-day course with extended hours.

GK# 7225 Vendor# AJEX & AJER

Course Overview


In this advanced hands-on course, you will prepare for your JNCIP-ENT certification by experiencing both the AJEX and AJER courses. You will cover the AJEX portion through virtual LAN (VLAN) operations, Multiple Spanning Tree Protocol (MSTP) and VLAN Spanning Tree Protocol (VSTP), authentication and access control for Layer 2 networks, IP telephony features, Class of Service (CoS), monitoring and troubleshooting tools, and features supported on the EX 4300 Series Ethernet switches. 

In the AJER portion, you will examine and work with the tools required to implement, monitor, and troubleshoot Layer 3 components in an enterprise network. You will cover Open Shortest Path First (OSPF), Border Gateway Protocol (BGP), and Class of Service (CoS) with a strong emphasis on multicast. Through demonstrations and hands-on labs, you will gain experience configuring and monitoring the Juniper Networks Junos operating system as well as monitoring device and protocol operations.
