I agree with Johanna. SSM is cleaner for VoD delivery.

I’m not sure about B. It might complicate things with multiple RPs.

Option B, PIM ASM with Auto-RP, seems good too. It automates the RP discovery process.

I feel like option C, PIM SSM, is more efficient for VoD. It reduces unnecessary traffic.

I’m leaning towards option D, PIM ASM with BSR. It simplifies the multicast group management.

I think option A, MSDP, is the best choice. It allows for multicast across different domains.

Wait, why not just use BSR instead?

I bet the network architect is just hoping the clients don't demand "video on instant" delivery. That would really put their design to the test!

Hmm, I wonder if the network architect has a good sense of humor. Maybe they'll throw in a joke about "video on demand" being "video on delay" if the network isn't set up properly.

Option D with PIM ASM and BSR could also work, but I'm not sure if it's the best fit for this specific setup.

Option B seems like the way to go. PIM ASM with Auto-RP should handle the VoD content delivery nicely.

I think BSR might be the right answer since it helps with scalability in larger networks, but I’m not entirely confident.

I’m a bit confused about whether to go with PIM SSM or PIM ASM. I need to recall the differences better.

This question feels similar to one we practiced on PIM configurations. I think PIM ASM with Auto-RP could be a good fit.

Hmm, I'm not entirely sure. I'll need to carefully weigh the pros and cons of each option and think through how they would work in this specific network setup. Time to do some deeper research on multicast routing protocols.

Based on the information provided, I'm leaning towards PIM ASM with Auto-RP. The fact that R2 has been selected as the RP suggests this might be the appropriate solution to deliver the VoD content.

I'm a bit confused by the options. MSDP, PIM ASM, PIM SSM - which one is the right choice here? I'll need to refresh my understanding of the differences between these protocols.

Okay, the key details seem to be that there are two offices in a separate multicast domain connected by a WAN link, and BGP is already set up. I think I need to focus on the multicast routing protocol that can handle this scenario.
