What configuration is required on the CE device when using MC-LAG?

  1. The CE must be configured with an MC-LAG to both PE devices.
  2. The CE must be configured with LACP in active mode.
  3. There is no configuration required on the CE.
  4. The CE must be an Alcatel-Lucent 7750 SR.

Answer(s): B



Why should you configure send-flush-on failure on your PE routers when using active/standby pseudowires?

  1. It flushes the local FDB speeding recovery
  2. It discards all packets in the queue and sends icmp-discad messages to the sender. The packets are re-transmitted resulting in no loss of data.
  3. On failure, the PE sends an LDP flush-all-from-me message to all PE devices in the VPLS. This speeds convergence to the new topology.
  4. It is not important to use send-flush-on-failure as Active/Standby signalling automatically converges the FDB in all VPLS instances

Answer(s): C



Which physical topology is NOT commonly deployed in today's VPLS networks?

Answer(s): D



Which of the following is a function of the data plane that must be considered when provisioning a VPLS service?

  3. Number of SDPs.
  4. MAC address consumption in the FDB.
  5. Bandwidth and replication requirements.

Answer(s): E
