I think making Area 0 L2-only could also be a good solution to ensure network continuity.

But making R3 an L1L2 router would provide better network continuity in case of link failure.

Hmm, this is a tricky one. I'm gonna have to go with B, because it seems like the most flexible and robust solution. Gotta love those L1L2 routers, am I right?

I disagree, I believe making R11 an L2 router would be a better option.

C) Make Area 0 L2-only. This way, the network can still function even if the link between R1 and R2 fails, since the L2 area will remain intact.

So, making Area 0 L2-only is the best solution for ensuring network continuity in this scenario.

That makes sense. Having Area 0 as L2-only would definitely help with network continuity.

B) Make R3 an L1L2 router. This solution ensures network continuity by allowing R3 to communicate with both the L1 and L2 areas, providing a redundant path if the link between R1 and R2 goes down.
