VPLS Features

Which of these statements about VPLS is false?

  • A A VPLS is a multipoint Layer 2 service.
  • B A VPLS allows multiple customer sites to be connected in a single bridged domain.
  • C A VPLS on a single node requires a SDP.
  • D With an IP/MPLS infrastructure, service providers can provide multiple VPLS services over a common IP/MPLS infrastructure.
  • E The VPLS switches traffic based on MAC address associated to the appropriate SAP.
Explanation

A Service Distribution Point (SDP) is used to bind a VPLS service to remote, far-end devices. A single-node VPLS can bridge traffic among its local Service Access Points (SAPs) without any remote connectivity, so it does not require an SDP. VPLS forwarding is based on learned MAC-address associations with SAPs or SDPs. Nokia: Virtual Private LAN Service
