• Question 91:

  On a MPLS network, switches can distribute labels. Which of the following statements regarding label distribution control mode is true?

  A. The downstream LSR determines a label bound to a specific FEC, and then notifies the upstream LSR.
  B. In Downstream on Demand (DoD) mode, an LSR distributes a label to an FEC without having to receive the label request message from its upstream LSR.
