Wait, is it really the unicast IP? That seems off.

I thought it was the unicast IP address of the interface?

224.0.0.6 is for OSPF DR/BDR, not updates!

It's definitely 224.0.0.5 for OSPF updates.

I’m leaning towards option C, but I could be mixing it up with another protocol. OSPF is tricky!

I feel like the answer might be related to the router's system address, but that doesn't sound right for OSPF updates.

I remember practicing a question like this, and I think it was about the multicast addresses. Was it 224.0.0.5 or 224.0.0.6?

I think the source IP address in an OSPF update is the unicast IP address of the interface, but I'm not entirely sure.

I'm not entirely confident on this, but I think the source IP address is the system address of the router sending the update, so I'll go with option D.

Ah, I remember this from my CCNA studies! The source IP address for OSPF updates is 224.0.0.5, which is the All OSPF Routers multicast address. Option A is the correct answer.

Hmm, I'm a bit confused on this one. I know OSPF uses multicast addresses, but I can't quite remember which one is used for the updates. I'll have to think this through carefully.

I'm pretty sure the source IP address in an OSPF update is the unicast IP address of the interface the update is sent on, so I'll go with option C.

Ah, I remember this from my OSPF studies. The update is sent to the multicast address, but the source IP is the unicast address of the interface. C is the way to go.

Multicast for updates, but unicast for the source.

Definitely! The source IP is the unicast address.

I don't think it's the system address. It makes more sense for it to be the interface IP address.

I'm not sure. I think it might be the system address of the router.

Hmm, the source IP address in an OSPF update is the unicast IP address of the interface the update is sent on. C is the correct answer for sure.

I agree with Ranee. The source IP address should be the unicast IP address of the interface.
