JNCIP-ENT Enterprise Routing and Switching Certification Boot Camp

  • Individuals responsible for configuring and monitoring EX Series switches
  • Individuals responsible for configuring and monitoring devices running the Junos OS
  • Anyone pursuing a JNCIP-ENT certification


  • Introduction to the Junos Operating System (IJOS)
  • Junos Routing Essentials (JRE)
  • Junos Enterprise Switching (JEX)
  • Junos Intermediate Routing (JIR)

Expected Duration
5 day


In this 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 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 Junos operating system as well as monitoring device and protocol operations.
