VPLS training course by TONEX is a combination of knowledge training, case studies, examples, and systems analysis revealing the details of VPLS in a swift, comprehensive, and understandable way.

A Virtual Private LAN Service (VPLS) network is a Layer 2 multipoint VPN that emulates LAN services across a WAN. VPLS enables service providers to interconnect several customer sites (each being a LAN segment) over a packet-switched network, effectively making all the customer LAN segments behave as one single LAN. With VPLS, no routing interaction occurs between the customer and service provider, and the customer can run any type of Layer 3 protocol between sites.

VPLS can utilize Multiprotocol Label Switching (MPLS) to offermultipointEthernetconnectivity over a mesh of logical circuits or tunnels, with the added benefits of Traffic Engineering (TE), resilience, and failover. VPLS enables carriers and SPs to offer managed Ethernet VPN services easily and cost effectively.
