This three-day course provides students with the knowledge to troubleshoot switching, routing, and security features.

This course builds off the Juniper Technical Support Fundamentals (JTSF) and Junos Troubleshooting (JT) courses and helps network engineers further their network troubleshooting capabilities.

Key topics include troubleshooting dynamic routing protocols such as OSPF, IS-IS, BGP, switching protocols, Ethernet VPN–Virtual Extensible LAN (EVPN-VXLAN) network, MPLS, multicast, class of service (CoS), stateful firewall features, IPsec VPNs (site-to-site and remote access), chassis clusters, next-generation firewall features, and vSRX.

The course is based on Junos OS Release 23.1R1.

This is an advanced level course.

After successfully completing this course, you should be able to:

• Troubleshoot problems with OSPF routing protocol.

• Troubleshoot problems with IS-IS routing protocol.

• Troubleshoot problems with BGP routing protocol.

• Troubleshoot routing loops and route oscillations.

• Troubleshoot problems with switching protocols.

• Troubleshoot an EVPN-VXLAN setup.

• Demonstrate the ability to troubleshoot MPLS.

• Demonstrate the ability to troubleshoot native multicast.

• Demonstrate the ability to troubleshoot CoS.

• Troubleshoot stateful firewall inspection.

• Troubleshoot site-to-site IPsec VPNs.

• Troubleshoot remote access VPNs using Juniper Secure Connect.

• Troubleshoot chassis clusters.

• Troubleshoot next-generation firewall features.

• Troubleshoot vSRX.

This course benefits individuals responsible for troubleshooting Juniper devices running Junos OS, which includes network operators, engineers, administrators, support personnel, and reseller support personnel.
