Virtual Private LAN Services (VPLS) training provides a technical overview of VPLS. VPLS training covers technical aspects of VPLS, as a class of VPN that supports the connection of multiple sites in a single bridged domain over a managed IP/MPLS network.


Upon completion of this course, the attendees will be able to:

  • Udnerstand the benefits and rationale for VPLS
  • List and explain the applications of VPLS
  • Sketch the VPLS architecture
  • Describe the fucntional architecture of VPLS
  • Compare its operation to Ethernet and MPLS
  • Describe VPLS operation
  • List and explain VPLS protocols
