Junos Layer 2 VPNs
(Normal) The purpose of this three-day course is to equip students with the skills necessary to design, implement, and troubleshoot a variety of layer 2 MPLS VPNs, including pseudo wires (BGP L2VPNs, LDP L2Circuits, FEC 129, & CCC), virtual private LAN service (VPLS), and Ethernet VPN (EVPN). The hands-on labs in this course, which is based on Junos 21.2R1, provide extensive practice with CLI configuration, numerous examples of common errors, and the troubleshooting steps necessary to fix them.

Q: What is enterprise switching?
A: This means the enterprise network has a great core switch, with additional distribution layer switches which generally operate below it to bring all the information into the data center & after that, disseminate it out to the access layer where the end users are located & there is fewer data traffic.
Q: Is a router the switch?
A: switch connects several devices to create a network, and a router connects multiple switches, & their respective networks to form an even more extensive network. These networks may be in various locations or across multiple sites.
Q: What is Juno's Operating System?
A: Juniper Networks provides high-performance network devices that create a responsive & trusted environment for accelerating the deployment of services & applications over a single network. The Junos operating system (Junos OS) is the foundation of these high-performance networks.
Q: What is the infrastructure required to attend your training program?
A: To attend the training session, you should have operational Desktops or Laptops with the required specification and a good internet connection to access the labs.
