Advanced Junos Enterprise Routing (AJER) [ARR_JUN_AJER]

OVERVIEW

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.
