• Question 76:

  A network engineering team is in the process of designing a lab network for a customer demonstration. The design engineer wants to show that the resiliency of the MPLS traffic Engineering Fast Reroute solution has the same failover/ failback times as a traditional SONET/SDH network (around 50MSEC).
