Junos Layer 3 VPNs (JL3V)

CODE: JUN_JL3V

LENGTH: 3 day(s)

PRICE: £2,280.00

Description

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.

These 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.

These hands-on labs utilize Juniper Networks vMX Series devices using the Junos OS Release 19.4R1.10, and are also applicable to other MX Series devices.

The Junos Layer 3 VPNs (JL3V) course is an advanced-level course.
