  • Duration: 2 Days
  • Test Level: Advanced
  • Certifications: JNCIP-SP
  • Price: USD 1900
  • Exams: JN0-661

This two-day course is designed to provide students with MPLS-based Layer 2 virtual private network (VPN) knowledge and configuration examples. The course includes an overview of MPLS Layer 2 VPN concepts, such as BGP Layer 2 VPNs, LDP Layer 2 circuits, FEC 129 BGP autodiscovery, virtual private LAN service (VPLS), Ethernet VPN (EVPN), and Inter-AS Layer 2 VPNs. This course also covers Junos operating system-specific implementations of Layer 2 VPN instances, VPLS, and EVPNs. This course is based on the Junos OS Release 16.2R1.6. Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring the Junos OS and in device operations.

After successfully completing this course, you should be able to:
Define the term virtual private network.
Describe the business drivers for MPLS VPNs.
Describe the differences between Layer 2 VPNs and Layer 3 VPNs.
List advantages for the use of MPLS Layer 3 VPNs and Layer 2 VPNs.
