EDU-JUN-JL3V - Junos Layer 3 VPNs (JL3V)

DURATION
3 days

LEVEL
Basic

OBJECTIVES
This three-day course is designed to provide students with MPLS-based Layer 3 virtual private network (VPN) knowledge and configuration examples. The course includes an overview of MPLS Layer 3 VPN concepts, scaling Layer 3 VPNs, Internet access, Interprovider Layer 3 VPNs, and Multicast for Layer 3 VPNs. This course also covers Junos operating system-specific implementations of Layer 3 VPNs. The concepts are put into practice with a series of in-depth hands-on labs, which will allow participants to gain experience in configuring and monitoring Layer 3 VPNs on Junos OS devices.

PREREQUISITES
Students should have intermediate-level networking knowledge and an understanding of OSPF, ISIS, BGP, and Junos policy. Students should have experience configuring MPLS label-switched paths using Junos. Students should also attend the Introduction to the Junos Operating System (IJOS), Junos Intermediate Routing (JIR), and Junos MPLS Fundamentals (JMF) courses prior to attending this class.

WHO SHOULD ATTEND
This course benefits individuals responsible for configuring and monitoring devices running the Junos OS.
