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). In order to address both link failure and node failure within the lab typology network, which type of the MPLS TE tunnels must be considered for this demonstration?

Wait, are we sure about the 50MSEC timing? Seems a bit optimistic.

NHop tunnels are cool, but they don’t provide the same failover benefits.

I’m surprised this is even a question, isn’t FRR the standard for MPLS?
SA

Wait, are we sure it’s not A? Backup tunnels are usually reliable too.
CH

I think the Next-hop tunnel was mentioned in a practice question, but I don’t remember it being linked to failover times like the FRR Backup tunnel.
ME

I feel like the TE backup tunnel might be relevant too, but I can't recall the exact differences between them right now.
JO
Jolene

I remember discussing the FRR Backup tunnel in relation to fast reroute, so I’m leaning towards option C, but I could be wrong.

I think we practiced something similar in class about MPLS TE tunnels, but I'm not entirely sure which one is specifically for failover.
