Question #: 109
Topic #: 3

Click on the exhibit.

A fully loose LSP "toR6" is enabled with FRR protection. All links have the same cost. After the link between R2 and R4 goes down, FRR protection repairs the LSP and traffic traverses on R1-R2-R7-R8-R4-R6. Which of the following about this CSPF-enabled LSP on an Alcatel-Lucent 7750 SR is TRUE?

AThe LSP will stay on the current path indefinitely unless another failure occurs.

BThe LSP will stay on the current path until the resignal timer expires.

CThe LSP will switchover to R1-R2-R3-R5-R6 after the resignal timer expires.

DThe LSP will switchover to R1-R3-R5-R6 after the retry timer expires.

Option C looks promising, but I'm not convinced. Wouldn't the LSP just try to find the shortest path after the resignal timer expires? I'm going to have to think this one through a bit more.

Let's review the options again to make sure we understand the behavior correctly.

I agree, but I'm not sure if it will switch over to another path after that.

Haha, the question is talking about an Alcatel-Lucent 7750 SR, which sounds like a fancy piece of networking gear. I wonder if they have a 'Shake and Bake' version for the rest of us.

I'm not sure about this one. The question mentions FRR protection, so I'm guessing the LSP won't switch to a new path unless another failure occurs.

That makes sense. It's important to have protection in place in case of failures.

Option B seems like the correct answer. The LSP will stay on the current path until the resignal timer expires, after which it will re-optimize and find a new path.
