VPLS redundancy techniques

Which of the following represents a key advantage of active/standby pseudowires?

  • A The MDU does not need to support MPLS.
  • B T-LDP signaling is not required.
  • C Layer 2 loop prevention protocol such as RSTP is not required.
  • D The MDU is not aware of the active/standby configuration.
Explanation

Active/standby pseudowires provide redundancy and failover within the provider network while exposing only the active service path to the attached MDU. The MDU does not need awareness of the active/standby configuration or involvement in switching to the backup pseudowire.
