I see the logic in B being false too. Same ID, no connection.

I feel like A could be tricky, but I think it's true. R2 and R4 can connect.

I lean towards D being false. Routing loops are less likely with OSPF.

Agreed, B is definitely false. R1 and R2 can't be neighbors.

Routing loops are no joke, so D seems like the safest bet. Gotta love those OSPF network challenges!

Unique router IDs are a must for OSPF, otherwise you're just asking for trouble. I'll go with D.

Haha, looks like someone forgot to configure unique router IDs. I'd say D is the correct answer here.

A routing loop between R3 and R4 sounds plausible, but I need to double-check how OSPF handles those scenarios.

I feel like I saw a similar question about neighbor relationships in OSPF, but I can't recall if it was about default routes or router IDs.

I remember studying that OSPF requires unique router IDs, so I think R1 and R2 having the same ID is a problem.

I feel pretty confident about this one. The key is that the question is asking which statement is false. So I need to carefully evaluate each option and determine which one doesn't align with the given information.

Okay, let me try to break this down step-by-step. If R1 and R2 have the same router ID, that could prevent them from forming a neighbor relationship. But the default route config might override that. I'll need to consider all the possibilities.

The same router ID for R1 and R2 is definitely going to cause some issues. I'm going with D on this one.

Hmm, the default route configuration is an interesting twist. I think I need to think through how that might affect the routing between the routers.

I'm a bit confused by this question. The router IDs being the same seems like it could cause issues, but I'm not sure exactly how that would impact the neighbor relationships.
