Which architecture does not require an explicit multicast signaling protocol, such as PIM or P2MP, to signal the multicast state hop-by-hop, but instead uses a link state protocol to advertise the multicast forwarding state?

Just to clarify, does this mean no extra signaling is needed?

Wait, is it really C? I thought it could be D.

I agree, C is the right answer!

No way, it’s not D. C is the one that fits!

It's definitely C, Bit indexed explicit replication.

I vaguely remember that "bi-directional" might relate to implicit methods, so I’m leaning towards D, but I need to double-check my notes.

I’m a bit confused about the terms used here. I thought all multicast protocols needed some kind of signaling, but maybe not in this case?

This question seems similar to one we practiced on multicast routing; I feel like it might be D, but I can't recall the details.

I think I remember something about link state protocols, but I'm not sure which option fits that description.

This question is testing our understanding of multicast routing concepts. I'll need to carefully consider each option and think about the differences between the architectures.

I'm pretty confident I know the answer to this one. The architecture that fits the description is Bit indexed explicit replication (BIER).

Okay, I think I've got this. The key is to identify the architecture that uses a link state protocol instead of an explicit multicast signaling protocol. Let me work through the options.

Hmm, I'm a bit confused by the terminology in this question. I'll need to review my notes on multicast routing architectures.

This is a tricky one. I'll need to think through the different multicast signaling protocols and how they relate to link state protocols.

I don't know, but I hope the answer isn't 'all of the above' - that would be a real multicast mess!

C. Bit indexed explicit replication, because who doesn't love a good bit index?

I'm not sure, but I think D) Bi-directional implicit replication could also be a possibility.
JA
Jarvis

I agree with Oneida, because BIER does not require explicit multicast signaling protocols.
NO

Hmm, this question is a bit tricky. I'm going to have to think about it more.

D. Bi-directional implicit replication sounds like the one that uses a link state protocol instead of multicast signaling.

I think the answer is C. Bit indexed explicit replication doesn't require a multicast signaling protocol.
EA

Yes, it eliminates the need for explicit multicast signaling protocols like PIM or P2MP.
EL
Elza

That makes sense, it uses a link state protocol to advertise the multicast forwarding state.
FA

I agree, C) Bit indexed explicit replication is the correct answer.
