Alright, let's think this through. If multi-topology is enabled, then the routers should have separate routing tables for IPv4 and IPv6. So the answer has to be option C, the routing table of R3 contains the route 2000::/128.

No, option D is actually true. The routing table of R2 contains the route 2000::/128.

But what about option D? Could that also be false?

Haha, I bet the guy who wrote this question is just trying to trip us up with that 2000::/128 route on R3. Nice try, but I'm not falling for it!

I'm pretty sure the routing table of R1 and R2 should both contain the route 2000::/64 since they have the summary command configured.

Exactly. R3 will have the specific route to the Loopback0 address of R4.

So, R3 should have the route 2000::/128 in its routing table, right?

Yes, that's correct. The summary command creates a summary route for the specified prefix.

I agree with Jutta. R2 should not have the route 2000::/128.

Wait, why would the routing table of R3 contain the route 2000::/128? That doesn't make sense, since the summary command is configured only on R1 and R2.

That could be possible, R3 might have another source for that specific route.

Maybe R3 learned about the /128 route through a different protocol or interface.

R3 might still have the /128 route if there's another way for it to learn about it.

R1 and R2 have the summary command, so R3 shouldn't have the /128 route.
