How can R2 have both /64 and /128? Sounds confusing!

I’m leaning towards option D being false since R2 should only have the /64 summary and not the /128, but I could be mistaken.

I practiced a similar question where the summary route was crucial. I feel like R3 having the /128 route might be the false statement here.

I think R2 should definitely have the /64 route because of the summary command, but I'm a bit confused about R3's routing table.

I remember studying multi-topology routing, but I'm not sure if R1 would have the /64 route since it's a summary route.

The question is asking which statement is false, so I need to carefully analyze each option. The routing table contents for each router will be important to determine the correct answer.

I'm a bit confused about the multi-topology aspect. Does that affect how the summary route is handled? I'll need to review that concept before deciding on the answer.

Okay, let's break this down step-by-step. The key information is that multi-topology is enabled and the 2000::/64 summary is configured on R1 and R2. I think the answer has to do with how that summary route is propagated.

This seems straightforward enough. If the admin is recommended to assign a machine account, then the answer must be True. I'll go with that.

Okay, let me see here. I remember reading something about access tokens expiring after a certain time period, but I can't remember if it was 24 hours or one hour. I'll have to eliminate the other options and make an educated guess.

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.

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.

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.
