Introduction

This accelerated Boot Camp prepares you for the JNCIS-ENT exam and provides experience configuring and monitoring Junos OS devices.

In this accelerated Boot Camp, you will gain the routing and switching knowledge needed for success on the Juniper Networks Certified Internet Specialist – Enterprise Routing and Switching (JNCIS-ENT) exam, and you will gain the hands-on experience needed to configure and monitor the Junos OS and monitoring device operations.

You will review switching concepts and operations, virtual LANs (VLANs), the Spanning Tree Protocol (STP), port and device security features, and high availability (HA) features.

Later, you will cover protocol-independent routing features, load balancing and filter-based forwarding, Open Shortest Path First (OSPF), Border Gateway Protocol (BGP), and IP tunneling.
