VPLS Features

Which data-plane service component uniquely identifies a VPLS at the far-end PE node?

  • A SDP id
  • B Service ID
  • C VC Label
  • D Tunnel Label
  • E Customer id
Explanation

The inner VC label identifies the VPLS service instance at the far-end PE after the outer transport/tunnel label is removed. The tunnel label is used for transport across the MPLS core, not for VPLS service identification.
