This five-day course is designed to provide 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, enterprise architecture, and Ethernet VPN-Virtual
Extensible LAN (EVPN-VXLAN) is covered in depth. The course also 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, vSRX virtual firewalls and vQFX virtual switches. This course is based on Junos OS Release 22.1R1.10.
