This three-day course is designed to provide students with the knowledge required to design, implement, and troubleshoot a wide variety of layer 2 MPLS VPNs, including pseudowires (BGP L2VPNs, LDP L2Circuits, FEC 129, and CCC), virtual private LAN service (VPLS), and Ethernet VPN (EVPN).
This course is based on Junos 21.2R1 and contains hands-on labs that gives extensive CLI configuration practice as well as many examples of common errors, and the troubleshooting steps required to fix them.
The Junos Layer 2 VPNs (JL2V) course is an intermediate-to-advanced level course.
