CODE: JUN_JL2V

LENGTH: 2 day(s)

PRICE: €1 600,00

Description

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. 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 2 VPNs, VPLS, and EVPNs on Junos OS devices utilizing the
Junos OS Release 16.2R1.6.

Course will be delivered using latest available course material version offered by Juniper
