Juniper Networks Certified Specialist Routing & Switching


For network engineers who need to increase their value to employers and stay current with advances in networking knowledge and skills, the JUNIPER JNCIS enterprise routing and switching certification program provides the education and training required for installing, monitoring, and troubleshooting network infrastructure products designed by the industry leader in IP networking.

Following are the lists of training recommended by JUNIPER to pass the JNCIS certification

The JNOS Intermediate Routing (JIR) course provides students with intermediate routing knowledge and configuration examples. The course includes an overview of protocol-independent routing features, load balancing and filter-based forwarding, OSPF, BGP, IP tunneling, and high availability (HA) features.

Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring the Junos OS and monitoring device operations. This course uses Juniper Networks SRX Series Services Gateways 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 Junos OS Release 12.1R1.9.

The Junos Enterprise Switching (JEX) is a two-day course that provides students with intermediate switching knowledge and configuration examples. This course includes an overview of switching concepts and operations, virtual LANs (VLANs), the Spanning Tree Protocol (STP), port and device security features, and high availability (HA) features.

This course is based on the Junos OS Release 12.2R1.8.
