A vc-label is signaled for each service, right?

Wait, so the vc-id actually maps traffic? That's interesting!

Multiple SDPs are definitely needed for that!

I feel like option D might be right since vc-id seems to relate to how traffic is mapped, but I can't recall the details.

I remember something about how MPLS can handle multiple services, but I'm not sure if it's through SDPs or something else.

The key here is that MPLS uses a vc-label to map the traffic to the appropriate service. So even though the traffic is carried over the same LSPs, the vc-label allows the services to be differentiated in the data plane.

I'm a bit confused on this one. I know MPLS is used to carry multiple services, but I'm not sure how the LSPs and vc-labels work together to make that possible. I'll need to review my notes.

Okay, I think I know the answer to this one. MPLS allows multiple services to be carried over the same LSPs by using vc-labels to identify the individual services.

This seems like a tricky question. I'll need to think through the MPLS concepts carefully to figure out the right approach.

So, if I have multiple services on the same MPLS LSP, can I call it a 'multi-service-plex'? No? Alright, I'll see myself out.

A) Multiple SDPs must be configured and bound to the LSPs for this to be possible. Well, that's one way to do it, but I'd bet there's a more elegant solution.

B) It is not possible to carry multiple services over the same MPLS LSPs? Really? That's just silly. Of course you can, otherwise MPLS would be pretty useless.

C) A vc-label is signaled per service. That's the right answer, as it allows each service to be mapped to a unique vc-label within the MPLS LSP.
