Why would they suggest changing to IGMP v3? That seems odd.

Definitely need to check the PIM settings on RA.

Isn't it surprising that RA is the one having issues?

I disagree, I think option C makes more sense.

Looks like option B is the way to go!

I'm leaning towards option B, but I need to double-check if the RP address is correct for our scenario.

I feel like removing the default SSM config could help, but I can't recall if that's the best move.

I think we practiced a similar question where we had to change IGMP versions. Could it be option C?

I remember something about configuring PIM for multicast, but I'm not sure if SSM is the right approach here.
LY

Ugh, I'm a bit confused by all the PIM and IGMP settings. I'll need to review my notes on multicast routing to make sure I understand the right approach here.

Okay, let's see. The key seems to be that RC is receiving the subscription messages, so the issue must be on RA. I'm thinking option A might be the way to go, but I'll double-check the other choices just to be sure.

Hmm, this looks like a tricky one. I'll need to carefully read through the details and think about the different PIM and IGMP configurations that could be causing the issue.

Alright, I've got a strategy. I'll eliminate the options that don't seem relevant, like changing the IGMP version or using bidir-PIM. Then I'll focus on the PIM SSM and RP-address settings to figure out the best solution.

I'm feeling pretty confident about this one. The key is that for a service composition, you need at least two participating services. So the correct answer is A, two.

Hmm, this question is as clear as mud. I'm going with Option A and hoping for the best. Maybe I'll get partial credit if I'm wrong.

Well, if it ain't broke, don't fix it. Just remove the default SSM config and add the RP, right? Option B is the way to go, folks.
LA

Thanks for the input, I'll go ahead and make that change on router RA.
GL
Glenna

Agreed, that should do the trick. No need to change anything else.
CA

Option B is definitely the solution here. Just replace the default SSM config with the RP address.

I'm not sure, but I think changing ip igmp version 2 to ip igmp version 3 on interface GigabitEthernet 1/0 could also work.
KA
Kayleigh

Hold up, why would we need to configure BIDIR-PIM? That seems overkill for this scenario. I'd go with Option A.
TO
Toi

User4: Good call, let's configure ip pim ssm with ip igmp version 2 on interface GigabitEthernet 1/0.
AM
Amina

Option A it is then, let's go with that.
AL
Aliza

Yeah, BIDIR-PIM might be too much for this issue.
KA
Kanisha

I agree, Option A seems like the most appropriate choice.
AR
Argelia

I agree with Tori, that seems like the most appropriate solution to the problem.
PH
Phuong

I think Option C is the way to go. Upgrading to IGMP v3 should resolve the multicast subscription problem.
JU
Justine

Option A looks like the right choice, configuring PIM SSM with IGMP v2 should fix the issue.
PE
Pearly

Agreed, let's make that change on router RA.
MI
Mireya

Let's go with option A then.
LA
Launa

Yeah, configuring PIM SSM with IGMP v2 should solve the problem.
NU

I think the correct action is to configure ip pim ssm with ip igmp version 2 on interface GigabitEthernet 1/0.
