I'm just going to flip a coin on this one. These OSPF questions always make my head spin. Heads I choose A, tails I choose B. Wait, which one was the correct answer again?

I believe it's D, the system address of the router.

Hold up, hold up! If the source IP address was the router's system address, then how would the other routers know it's an OSPF update and not just some random traffic? I'm sticking with 224.0.0.5, the OSPF multicast address.

Actually, the source IP address in an OSPF update is 224.0.0.5, you're right.

But wouldn't that be confusing for the other routers? I believe it's 224.0.0.5, the OSPF multicast address.

Hmm, I'm gonna have to go with option D. The system address of the router, because why would it use a multicast address when it can just use its own address? This question is trying to trick us!

I agree with you, option C does seem like the most logical choice here.

I think it's actually option C. The unicast IP address of the interface makes more sense to me.

I'm not sure, but I think it could also be the system address of the router.

I agree with Lezlie, it makes sense that the update would come from the interface's IP address.

I think it's option C - the unicast IP address of the interface the update is being sent on. That makes sense since OSPF updates are sent directly to the neighboring routers.

The source IP address in an OSPF update is 224.0.0.5, which is the multicast address used by OSPF routers to communicate with each other. Easy peasy!
