This course provides students with the tools and methods required for implementing, monitoring, and troubleshooting Layer 3 components in an enterprise network. This course covers OSPF, BGP, multicast, and enterprise architecture. This course also covers Ethernet VPN–Virtual Extensible LAN (EVPN-VXLAN) in depth. The course exposes students to common troubleshooting commands and tools used to diagnose various intermediate to advanced issues.

Through demonstrations and hands-on labs, students will gain experience with features of each of these devices, Juniper Networks® vSRX Virtual Firewalls and Juniper Networks® vEX Virtual Switches. This course also includes a virtual nested environment for demonstrating EVPN-VXLAN operations. The course is based on Junos OS Release 25.2R1.9.
