Address aggregation sounds familiar, but I can't recall how it specifically helps with OSPF convergence times.

I remember a practice question where we had to choose between hub-and-spoke designs and full mesh. Hub-and-spoke seemed more efficient for this scenario.

I think using a single address per router for all P2P links could help with address conservation, but I'm not entirely sure if that's the best option.
